New ladder leaders West Coast could be without midfielders Luke Shuey and Elliot Yeo for Sunday's clash with Hawthorn.
The Eagles, who have won eight games in a row and took over at the top by beating Richmond at Optus Stadium on Sunday, also have Jeremy McGovern in doubt.
Shuey and Yeo are rated no better than 50-50 chances to face the Hawks at Etihad Stadium.
After missing the past two games with a hamstring strain, Shuey is pushing for a return.
He took part in skills work at Subiaco Oval on Monday and if he gets through training over the rest of the week the onballer will be in contention.
Reigning club champion Yeo, who was outstanding in the win over the reigning premiers, wore a compression bandage on his right knee at training on Monday.
He came out of the game late in the first quarter against the Tigers but returned to the action early in the second term and went on to amass 29 disposals and nine clearances in the 47-point victory.
Coach Adam Simpson said: "We didn't do too much today at training, it was the day after a game, so we won't know on Elliot until tomorrow.
"I can't give you too much, but I think Luke might be 50-50 and the same with Elliot."
Star intercept defender McGovern could need to dash back to Perth to be at the birth of his child.
The Eagles haven't beaten Hawthorn in Melbourne for 12 years, but have a better record against the Hawks at Etihad Stadium than they do at the MCG where they've lost the last three meetings by 46 points or more.
West Coast are 3/4 to beat Hawthorn, who are 23/20.
