Collingwood v Sydney: It seems like Jarred Moore badly hurt his ribs in Q2.
St Kilda v North Melbourne: Saints midfielder Lenny Hayes is the worry as he was a late change.
Richmond v Hawthorn: no changes but Tigers defender Will Thursfield seemed to dislocate his shoulder early on. Ben Cousins got cleaned up late and missed Q4, while Chris Newman's knee restricted his output.
Brisbane Lions v Port Adelaide: Port's Robbie Gray was a late withdrawal. Cheynee Stiller got knocked out and was gone, while Daniel Merrett limped around for awhile with an ankle complaint.
Adelaide v West Coast: Crows onballer Rob Shirley did his hammy in Q3 and finished up for the game.
Carlton v Melbourne: Carlton's Dennis Armfield (ankle) was a late change. Ricky Petterd was mothballed early with a groin complaint. Also Carlton's Richard Hadley suffered an arm injury and was taken to hospital. Reportedly x-rays have confirmed it is a broken ulna which will require immobilisation suggesting his season is year.
Western Bulldogs v Geelong: Worryingly for DT coaches Paul Chapman missed pretty much half the game with hamstring tightness and it's not clear if he'll play in Round 22.
