It appears whatever damage Rohan sustained occurred in a mid-air collision at a marking contest rather than when he landed, which lessens the chance of a possible rupture to his anterior cruciate ligament. Should he escape with bone bruising he would be at long odds to play in the grand final, should the Swans qualify. Rohan has endured a wretched run with injury, most notably a horrific broken leg in 2012 that cost him the chance to play in that year's premiership team.

It's understood McVeigh remains hopeful he will be available for the decider despite limping off in the second quarter with a calf injury. The veteran returned to the field briefly in the third quarter but played only several minutes before being sent back to the bench. Calf issues are notoriously difficult to overcome, particularly for veteran athletes, but McVeigh will give himself every chance to return. It is turning out to be a torrid finals series for the Swans, who lost Tippett and Callum Mills to injury in the qualifying loss to Greater Western Sydney. Tippett, who trained last Thursday and over the weekend, has shown he can play through pain, having made a quick recovery from hand surgery last year. Ruckman Toby Nankervis would be the unlucky big man to make way for Tippett after an aggressive effort against Adelaide. Mills has not been ruled out but it would be a big risk to play the youngster 13 days after a hamstring injury, albeit a low-grade strain.

The enigmatic Dean Towers, with his speed and marking ability, shapes as the logical replacement for Rohan in the Swans forward line. The pacy Harry Cunningham is in the frame to replace McVeigh, along with Zak Jones, who suffered a nasty concussion in the NEAFL grand final two weekends ago. Despite finishing the home and away season as minor premiers, the Swans have only a six-day break before taking on the Cats after forfeiting their advantage with their loss to the Giants. The Swans also came off a short week when they upset the Cats in Geelong earlier this year. "It's a prelim final and I think one of the features of our team this year has been the guys that have been able to come in and play a role," Swans midfielder Josh Kennedy said. Loading

"It was certainly a tough game, certainly pretty exhausted by the final siren. They were in a similar position Adelaide. You'd play after a three-day break going into a prelim final, everyone's sort of walking on cloud nine at the moment." After disappointing against the Giants, the Swans were back to their best, shocking the Crows with their manic attack on the ball. Kennedy led the charge with 42 possessions in a best-on-ground performance.
