J Fraser (Collingwood) kneeInitially thought to have a serious posterior cruciate injury, but further assessment indicated a minor strain. Will almost certainly miss this week but could be OK after that.

D Kerr (West Coast) ankleCopped a nasty knock to the ankle in the first quarter on Saturday night and took no further part in the game. He has aggravated an old ankle injury and will not be able to train for two to three weeks.

C Bolton (Syd)concussionLeft dazed after a clash in the first quarter on Saturday night but should recover in time for this week's game.

D Milburn (Geel)shoulderHad some shoulder soreness after Saturday night's game but is likely to be available this week.

C Jones (West Coast)ankleSustained a high ankle sprain at training on Friday and is likely to miss 3-4 weeks.
