Sicily was assisted off the ground late into the fourth quarter of Hawthorn’s 32-point loss to the Eagles, with coach Alastair Clarkson fearing the worst.
“We’re uncertain at this stage. He’s got an unstable knee, so that’s not a good sign,” Clarkson said.
“We’ll get that scanned in Adelaide on Tuesday and see where it goes, but the mechanism didn’t look great and the fact he has instability there – it can’t be confirmed until the scan, but it’s looking uncomfortable for us and for (Sicily).
“It’s always disappointing … He’s a pretty resilient lad and these things happen in footy. You’ve just got to deal with that and get yourself back when you can.
“It’s either a medial or an ACL, so cross our fingers and hope for the best and see what the outcome is – but he’ll miss a period of time, no matter what.”
Hawthorn will play ladder leaders Port Adelaide in South Australia next Saturday.
