Cyril Rioli is likely to miss a month of football after his troublesome left hamstring again wreaked havoc during Hawthorn's commanding 53-point victory over the Gold Coast Suns in Launceston on Saturday.
Chasing after a loose ball in the middle of Aurora Stadium, Rioli fell to the ground after trying to extend himself. He was forced to sit out the game's latter stages, and now faces yet further time on the sidelines after re-injuring the left hamstring that kept him out of action in rounds 10 and 11.
"I think most times you say around a month when someone gives a hammy a bit of a nick. I don't think it's as significant a hamstring [as] Sam Mitchell's had," Hawthorn coach Brendon Bolton said.
Rioli now faces scans to reveal the extent of the damage. He has a history of soft-tissue issues and missed two months of football last year after tearing his right hamstring.
