- Cats lose four to injury, hand debut to younger Guthrie

- Ladder-leading Giants top up further with three stars

- Jed Lamb out with concussion amid six Blues changes

GEELONG has lost four players to injury ahead of its blockbuster with Greater Western Sydney, but has named skipper Joel Selwood for the Saturday night clash.

Scott Selwood (hamstring), Tom Stewart (facial fracture), George Horlin-Smith (ankle) and Darcy Lang (leg) will all miss the battle between the top-four sides, while a fitness cloud remains over Joel Selwood as he races the clock to play the Giants after last week's concussion.

The Cats will blood debutant Zach Guthrie, a clever defender who is the younger brother of midfielder Cam, while Lachie Henderson, Zac Smith and Aaron Black have also been selected.

The Giants will be bolstered by the return of an important trio, headlined by vital midfielder Josh Kelly, who is back after a week out with a hip injury. Devon Smith has been recalled from a long lay-off with a knee problem and Rory Lobb from a groin issue.

They replace injured pair Tim Taranto (ankle) and Harrison Himmelberg (finger), while Daniel Lloyd has been omitted for Saturday night's meeting with the Cats at Spotless Stadium.

Former co-captain Jarrad McVeigh will return to the Sydney side against Melbourne on Friday night after overcoming a hamstring injury, while Zak Jones is back after serving his one-match suspension.

Youngster Will Hayward will miss with a foot injury while ruckman Callum Sinclair has been dropped.

Melbourne has upgraded rookie defender Mitch White to the senior list and brought him in to face the Swans in the important battle, with Josh Wagner also in. But the Dees have lost crucial pair Christian Salem and Jeff Garlett to hamstring strains.

West Coast will head to Melbourne for Saturday's clash with the Western Bulldogs without skipper Shannon Hurn (concussion), Brownlow medallist Matt Priddis (soreness) and Josh Hill (illness).

After beating his suspension at the AFL Tribunal, defender Will Schofield has been ruled out with a hip injury. Chris Masten, Jack Redden, Sharrod Wellingham and Sam Butler have been recalled by the Eagles for the important clash.

The Bulldogs have made just one change, with skipper Robert Murphy back from a hamstring injury and replacing Tom Liberatore, who will miss with a cork.

Carlton has made six changes for its Saturday afternoon clash with Adelaide at the MCG, with Ed Curnow (larynx) and Jed Lamb (concussion) to miss through injury and Blaine Boekhorst, Billie Smedts and Jarrod Pickett dropped. Sam Petrevski-Seton will miss through 'management'.

Lamb has not recovered after being struck by Richmond's Bachar Houli early in last week's loss.

Adelaide's long wait to have Mitch McGovern back in its forward line is over, with the high-flying target named to come up against the Blues. McGovern hasn't played since suffering a serious hamstring in round three.

Riley Knight and David Mackay are also back, with Tom Lynch (illness), Charlie Cameron (wrist) and Andy Otten (omitted) out of the side.

Gary Ablett's 300-game celebrations had to be put on hold for a week after he was a late withdrawal last week, but the Gold Coast champion is back for the Suns' meeting with North Melbourne at Metricon Stadium on Saturday as he reaches the milestone.

Ablett is joined by Matt Rosa and Ryan Davis in the Suns' line-up, with Matt Shaw, Jesse Joyce and Darcy MacPherson all dropped.

Mitch Hibberd and Corey Wagner have come in for the Roos, replacing Ben Cunnington (suspension) and Trent Dumont (managed).

Richmond will blood another new small forward, with exciting South Australian Tyson Stengle coming into the Tigers' side to face Port Adelaide.

Stengle replaces fellow goalkicker Shai Bolton, who has been rested, while Oleg Markov comes in for the suspended Houli.

Matthew Broadbent and Jared Polec have been brought into the Power side, with Aaron Young and Jake Neade cut.

Essendon is set to welcome back Cale Hooker and Darcy Parish for its clash with the Brisbane Lions at Etihad Stadium on Sunday, with Matthew Leuenberger and potential debutant Josh Begley also included in the Dons' squad.

Shaun McKernan, who kicked two goals last week as a replacement for Hooker, is the only Bomber to make way at this stage.

Dayne Beams' AC joint injury will keep him out of the Lions' line-up for about a month, but the club has named Cedric Cox, Marco Paparone and Jono Freeman in its extended squad, with Josh Walker named to play.

Collingwood's Josh Thomas is a chance to play his first senior game since serving his anti-doping ban. The midfielder is named on the extended bench for the Pies' contest with the Hawks on Sunday, alongside other potential inclusions Matt Scharenberg and Jackson Ramsay. Important forward Jamie Elliott will play, as will giant forward/ruck Mason Cox.

James Aish and Ben Crocker have been dropped by the Magpies, while Hawthorn has recalled premiership defender Ben Stratton from injury. Dallas Willsmore and Kurt Heatherley have also been included in the Hawks' extended squad.

Fremantle captain Nat Fyfe headlines the Dockers' changes for their meeting with St Kilda on Sunday at Domain Stadium, with ruckman Aaron Sandilands and Brady Grey also added to the 25-man squad. Both Fyfe and Sandilands are named in the starting lineup.

The Saints have added Jack Steele, Daniel McKenzie and Ben Long to their squad, all of whom are on an extended bench.
