ADELAIDE

Player Injury Estimated Return Eddie Betts Ribs Test Tom Doedee Knee Season Cam Ellis-Yolmen Shin 1-2 weeks Kyle Hartigan Ankle Test Paul Hunter Foot 6 weeks Alex Keath Ankle Test Ned McHenry Back 2-4 weeks Andrew McPherson Hamstring 4-5 weeks Updated: Tuesday, August 6

Early prognosis Keath is expected to return for Sunday's important encounter with West Coast in Perth. The key defender has missed the past two games with ankle soreness. Betts and Hartigan are both expected to be available to face the Eagles after sustaining injuries in last weekend's 22-point win against St Kilda. Betts copped a knee to the ribs in the second quarter, while Hartigan rolled his ankle in a marking contest. He'll be managed early in the week before being tested at the Crows' main training session on Thursday. Ellis-Yolmen is at least another week away from returning from a shin injury that has kept the big-bodied midfielder sidelined since round 13. - Lee Gaskin

BRISBANE

Player Injury Estimated Return Tom Cutler Foot 1 week Mitch Hinge Hamstring Test Tom Joyce Shin 5 weeks Dayne Zorko Hamstring Test Updated: Tuesday, August 6

Early prognosis All eyes will be on Zorko this week. His scan results came back clear, but the skipper will still need to pass a fitness test to play. - Michael Whiting

CARLTON

Player Injury Estimated Return Charlie Curnow Knee Season Sam Docherty Knee Season Pat Kerr Shoulder Season Matthew Kreuzer Hip Test Kym LeBois Hamstring 2-3 weeks Caleb Marchbank Neck Season Mitch McGovern Conditioning Test Tom Williamson Back Season Updated: Tuesday, August 6

Early prognosis The Blues are hopeful McGovern will return to football this week after a solid four-week training block, though haven't ruled out the prospect of bringing him back through the VFL. The club also believes Kreuzer will return from hip soreness. - Riley Beveridge

COLLINGWOOD

Player Injury Estimated Return James Aish Shoulder 2-3 weeks Dayne Beams Shoulder/Hip Season Mason Cox Eye Season Jordan De Goey Hamstring 1 week Lynden Dunn Knee Season Will Kelly Hamstring TBC Tom Langdon Knee Season Darcy Moore Hamstring 2-3 weeks Nathan Murphy Back Test Sam Murray Provisional ASADA suspension TBC Isaac Quaynor Foot TBC Ben Reid Hamstring TBC Brayden Sier Calf TBC Jaidyn Stephenson Suspended 3 weeks Daniel Wells Knee Test Updated: Tuesday, August 6

Early prognosis Cox's season-ending eye injury has added to the Pies' personnel woes but Wells could return at VFL level. De Goey and Quaynor will remain on the sidelines at least for the short term, while Aish and Moore also hope to be back before the end of the minor rounds. Sier seems unlikely again this week while Murphy again didn't take the field in the VFL after being cleared to play. Kelly is also being managed conservatively, but Reid faces an uphill battle to play again this season after another setback. Stephenson will be available at finals time but the campaign is over for Langdon and veterans Dunn and Beams. - Ben Collins

ESSENDON

Player Injury Estimated Return Tom Bellchambers Calf 2-3 weeks Joe Daniher Groin Season Sam Draper Knee Season Aaron Francis Neck Test Dyson Heppell Foot Test Michael Hurley Shoulder 3-4 weeks Matt Guelfi Knee Season Jayden Laverde Nose Available Shaun McKernan Illness Available Irving Mosquito Hamstring 1-2 weeks Kobe Mutch Knee TBC Darcy Parish Concussion Test Adam Saad Hamstring 2 weeks Devon Smith Knee Season James Stewart Groin Season Updated: Tuesday, August 6

Early prognosis The Bombers' injury list has grown markedly this week, losing Guelfi for the season to a training accident which required knee surgery, and important backman Saad to a minor hamstring strain. They will get McKernan back from illness and will be desperate for Heppell to be available, while Parish and Francis will also be monitored before being cleared for the clash. - Callum Twomey

FREMANTLE

Player Injury Estimated Return Brennan Cox Hip 1 week Stefan Giro Knee Season Stephen Hill Quad TBC Jesse Hogan Foot Season Rory Lobb Shoulder Season Lloyd Meek Foot Season Tom North Calf Test Alex Pearce Ankle Season Luke Ryan Hamstring 2 weeks Matt Taberner Foot Season Luke Valente Groin Season Tobe Watson Knee 2 weeks Nathan Wilson Toe TBC Updated: Tuesday, August 6

Early prognosis Lobb's season is over after undergoing shoulder surgery. A timeframe on Wilson is yet to be determined. Scott Jones made his return from a calf injury in the WAFL and got through unscathed. Ryan and Cox are still in the frame to return before the end of the season. Pearce spent time as an assistant coach for Peel Thunder last week as he recovers from an ankle injury. - Jourdan Canil

GEELONG

Player Injury Estimated Return Jordan Cunico Ankle 2-3 weeks Zach Guthrie Ankle Test Nathan Kreuger Knee Test Brandan Parfitt Back Test Gary Rohan Knee 2-4 weeks Updated: Tuesday, August 6

Early prognosis Scans on Monday confirmed Rohan would miss at least the next fortnight with his knee setback. Parfitt has now missed three matches with a back complaint and will be put through his paces to assess his availability on Wednesday. Kreuger and Guthrie are outside chances to return. - Mitch Cleary

GOLD COAST

Player Injury Estimated Return Callum Ah Chee Ankle 2 weeks Will Brodie Hamstring Season Sam Collins Hip Season Brayden Crossley Personal leave TBC Nick Holman Back Season Jack Hombsch Ankle Season Wil Powell Knee Season Izak Rankine Hip TBC Mitch Riordan Calf 1-2 weeks Rory Thompson Knee Season Harrison Wigg Knee Season Aaron Young Knee Test Updated: Tuesday, August 6

Early prognosis Not much news for the Suns, which is a good thing. Young has had a difficult season but is a chance to play NEAFL at the weekend. Ah Chee is progressing well and still a chance to return before the season finishes. - Michael Whiting

GREATER WESTERN SYDNEY

Player Injury Estimated Return Jeremy Cameron Calf Test Stephen Coniglio Knee 5 weeks Matt de Boer Shoulder Test Matt Flynn Knee Season Josh Kelly Calf Test Zac Langdon Ankle 5 weeks Jonathon Patton Knee TBC Sam Taylor Hamstring 3 weeks Callan Ward Knee Season Updated: Tuesday, August 6

Early prognosis Cameron, Kelly and de Boer could all be ready to face the Hawks on Friday night, but they'll have to train strongly on Wednesday to convince selectors to pick them. In further good news, Aidan Corr, Isaac Cumming and Xavier O'Halloran are all fit but won't play this weekend because of the Giants' NEAFL bye. - Adam Curley

HAWTHORN

Player Injury Estimated Return Grant Birchall Hamstring 2-3 weeks Will Golds Ankle 2-3 weeks Jarman Impey Knee Season Harry Jones Knee Season Darren Minchington Hamstring 3-5 weeks Tom Mitchell Broken leg Season Tim Mohr Dislocated knee/ACL Season Ryan Schoenmakers Calf 1-2 weeks Updated: Tuesday, August 6

Early prognosis Birchall's season may be over because of a hamstring setback on Friday night. However, the Hawks say they are pleased with him being able to play six games between VFL and AFL level, especially with his troublesome knee holding up well. Jack Scrimshaw (knee) resumed in the VFL on restricted minutes and will increase his game time this weekend. Tim O'Brien (calf), Harry Morrison (back) and Dylan Moore (groin) also returned from respective injuries as well. First-year midfielder Will Golds sprained an ankle at training last week. - Marc McGowan

MELBOURNE

Player Injury Estimated Return Jeff Garlett Shoulder Season Mitch Hannan Groin 1-2 weeks Neville Jetta Knee Season Kade Kolodjashnij Head Season Jake Lever Ankle Test Steven May Hamstring Test Tom McDonald Knee Season Aaron Nietschke Knee Season Joel Smith Groin Season Charlie Spargo Calf Test Tom Sparrow Knee 2-3 weeks Aaron vandenBerg Foot Season Guy Walker Shoulder Indefinite Sam Weideman Jaw/hip Season Updated: Tuesday, August 6

Early prognosis Key backs May and Lever are tests for this week's match against Collingwood, with Lever having rolled his ankle last round. Weideman is down to have operations on both hips, the first next week. McDonald's season is over but he is due to start running on the weight-bearing AlterG treadmill next week after surgery on a torn meniscus, while Nietschke has started incorporating agility work in his rehab from a knee reconstruction. - Sarah Black

NORTH MELBOURNE

Player Injury Estimated Return Shaun Atley Knee Test Luke Davies-Uniacke Shoulder Season Majak Daw Hamstring Season Aaron Hall Personal leave Indefinite Kyron Hayden Achilles Season Ben Jacobs Head/neck Season Luke McDonald Fractured fibula Season Tom McKenzie Back TBC Bailey Scott Foot Season Dom Tyson Calf Indefinite Ed Vickers-Willis Knee Season Will Walker Knee Season Declan Watson Knee Indefinite Sam Wright Hamstring/retirement Season Updated: Tuesday, August 6

Early prognosis The Roos have booked Davies-Uniacke in for a right shoulder reconstruction to fix an issue he suffered earlier in the season when fending off an opponent, bringing an end to his second AFL campaign. Watson's is a fresh injury and he will sit out at least this weekend to try to recover from a medial cruciate ligament setback in his left knee, the same knee he had reconstructed in mid-2017. Wright's farewell game ended prematurely when he sustained a hamstring injury, but he wasn't going to play again this year, anyway. Atley will try again to prove his fitness after hurting himself in round 19. - Marc McGowan

PORT ADELAIDE

Player Injury Estimated Return Ryan Burton Hamstring 1-2 weeks Zak Butters Bruised sternum Test Tobin Cox Kidney 2 weeks Brad Ebert Knee 4-6 weeks Jake Patmore Knee Season Jack Watts Leg Indefinite Updated: Tuesday, August 6

Early prognosis Butters is in doubt for Saturday's clash with Sydney after suffering a bruised sternum in the first half of last weekend's win against Essendon. Burton is on track to return from a hamstring injury before the end of the season after increasing his training loads. Watts has returned to running, but there isn't any timeframe on when he will be available. The utility hasn't played since breaking his leg and damaging his ankle in round two. - Lee Gaskin

RICHMOND

Player Injury Estimated Return Trent Cotchin Hamstring 1-2 weeks Jack Higgins Brain bleed Season Callum Moore Ankle Test Alex Rance Knee Season Sydney Stack Calf Test Updated: Tuesday, August 6

Early prognosis One of Richmond's shortest injury lists for the season at the right time of the year. Moore is a chance to make his return in the VFL from a fractured ankle this weekend. Stack is less likely to play against Carlton, with the club wanting to be cautious with a first-year player who has a soft-tissue injury. Cotchin is still a week or two away. - Sarah Black

ST KILDA

Player Injury Estimated Return Blake Acres Shoulder Test David Armitage Personal Indefinite Logan Austin Shoulder Indefinite Jack Bytel Back Season Jarryn Geary Leg Season Jade Gresham Eye socket 2-3 weeks Dan Hannebery Ill Test Dean Kent Quad Season Max King Ankle Season Billy Longer Concussion Season Paddy McCartin Concussion Season Jack Newnes Ill Test Ben Paton Ill Test Lewis Pierce Concussion Indefinite Dylan Roberton Heart Season Updated: Tuesday , August 6

Early prognosis Gresham could be sidelined for the rest of the season after suffering a fractured eye socket on the weekend. The Saints would expect Hannebery, Newnes and Paton to be right to go. However, considering Hannebery hasn't played at any level since June and has dealt with well-publicised soft-tissue issues, he might need to return via the VFL. - Dinny Navaratnam

SYDNEY

Player Injury Estimated Return Darcy Cameron Quad 1-2 weeks Harry Cunningham Groin Season Lance Franklin Hamstring 1-2 weeks Will Hayward Hip Season Matthew Ling Achilles 1-2 weeks Jack Maibaum Knee Season Jarrad McVeigh Calf 2 weeks Sam Naismith Iliotibial band 1 week Colin O'Riordan Groin Season Callum Sinclair Shoulder Season Nick Smith Hamstring Season Durak Tucker Hamstring TBC Updated: Tuesday, August 6

Early prognosis Star defender Rampe has been cleared by specialists to return against Port, after he missed the Sydney Derby with an eye injury. Superstar forward Lance Franklin will increase his training and could face Melbourne in round 22. Veteran McVeigh is hopeful of joining training next week with a look at playing again before he retires at the end of the year. The news isn't as positive for Naismith who is battling soreness, while O'Riordan isn't expected to play again this year. - Adam Curley

WEST COAST

Jarrod Brander Hamstring TBC Jamie Cripps Adductor Test Liam Duggan Ankle TBC Luke Foley Calf 1-2 weeks Nic Naitanui Ankle Indefinite Brodie Riach Leg TBC Josh Smith Hamstring 3-4 weeks Daniel Venables Concussion Season Updated: Tuesday, August 6

Early prognosis Cripps is eyeing a return against Adelaide on Sunday after making good progress in his recovery. Duggan is still being assessed after aggravating his original ankle ligament injury via a knock in the WAFL, while Brander's season could be over as the club investigates the possibility of surgery on his badly injured hamstring. Smith could be available for selection during the pre-finals bye after a quicker than expected rehab of his hamstring injury. - Riley Beveridge

WESTERN BULLDOGS

Player Injury Estimated Return Hayden Crozier Ankle Test Caleb Daniel Hamstring TBC Taylor Duryea Groin Test Ryan Gardner Knee 4-6 weeks Fergus Greene Shoulder Season Dale Morris Knee Season Josh Schache Concussion Test Mitch Wallis Ankle Indefinite Updated: Tuesday, August 6

Early prognosis Defender Daniel pulled up sore following the loss to Brisbane and scans have revealed some damage to his left hamstring. He will miss at least this week's clash against Essendon. Crozier will be tested later in the week after hurting his ankle last week. - Josh Schonafinger

*Placed on the club's long-term injury list
