Toby Nankervis is in doubt for ladder leaders Richmond ahead of their clash with West Coast.
The Tigers may have to go into meeting between the top two clubs without their No.1 big man, who picked up a wrist injury in the win over North Melbourne at the weekend.
Nankervis wasn't sighted at training at Punt Road on Wednesday, and cold be replaced by former rookie Ivan Soldo.
It would be a blow to Damien Hardwick's side to have to take on Eagles gun ruckman Nic Naitanui without Nankervis, who was hurt when he landed awkwardly after contesting a centre bounce against Todd Goldstein in the third quarter.
Speaking of the 23-year-old, who was able to play out the game against the Kangaroos, defender Nick Vlastuin said he had 'a couple of sore spots' but could still play against the Eagles.
Vlastuin added: "Ivan Soldo has been playing really well in the twos, so I'm not sure what selection is but if 'Nank' doesn't pull up, and I think he'll be alright, but if he doesn't pull up well I suppose Soldo will come in and fill a role.
"He's been following up really well at ground level in the twos so I'll be excited if 'Nank' doesn't pull up that Soldo gets a go but either way we're confident that our midfielders can probably nullify Nic Nat around the ground."
The Eagles, who trail Richmond on percentage, have Naitanui returning after a one-game suspension.
Richmond could have back-up ruckman Shaun Grigg returning after two games out with a hamstring problem.
Forward Jason Castagna (knock to the knee) missed Wednesday's training session, as did Dion Prestia who's likely to miss a second game with a calf problem.
Richmond are 100/111 to beat the Eagles, who are 20/21. The Tigers are 20/21 conceding a 1.5-points start.
