Tall utility Mark Blicavs is a key selection call for Geelong ahead of their must-win AFL match against Sydney.
Blicavs has played most of this season in defence and is the Cats' first choice to play on Swans superstar Lance Franklin.
But he was spotted wearing a moon boot over the weekend and Geelong coach Chris Scott said it is because of a toe injury.
Blicavs trained away from main group on Tuesday, but Scott expects him to play against the Swans.
"Franklin's clearly one of the best, if not the best, key forwards in the game so it would be a great challenge for Mark if he does get it," Scott said.
"Two pretty good athletes going at it, and I think Mark's certainly the type of person and player that would relish the challenge."
The Cats are set to regain Scott Selwood for the SCG clash, but scheduling problems mean they must wait another week for the return of forward Dan Menzel.
Defender Lachie Henderson also is closing on an AFL recall.
Geelong's back-to-back Thursday night games are broken up by a Sunday VFL game, limiting their selection options.
"It's just been a perfect storm because we have had a lot of well-credentialled players due to come back through this period," Scott said.
"It would have been difficult enough as it was but when you combine it with the fact of returning players it has been a little more difficult.
"If we can put in a polite request to the VFL and AFL fixturers to ensure that it doesn't happen again, hopefully that helps."
Young Swans star Isaac Heeney is likely to miss this week's match because of concussion.
Thursday night's clash is crucial for Geelong, who have dropped to eighth on the back of two losses.
