Richmond interceptor Nick Vlastuin could miss next week's must-win clash against Hawthorn with rib damage.
The tough defender was the victim of a Charlie Dixon knee to the side in a marking contest, and was subbed out of the Tigers' 38-point win, but did not need to go to hospital and watched the remainder of the game from the bench.
"He's probably doubtful, we suspect he has some form of rib damage," coach Damien Hardwick said.
"But once we know, you'll know. I'd say he's incredibly doubtful for next week."
