The Giants could receive a major boost for next week's grand final clash against Richmond, with injured stars Stephen Coniglio and Lachie Whitfield in the frame to return.
GWS coach Leon Cameron was hopeful that Coniglio and Whitfield would get up for the decider and that skipper Phil Davis will be fit.
Davis suffered finger and shoulder injuries in his side's preliminary final win over Collingwood.
"Phil's calf was a bit tight, but in saying that, whenever Phil gets a tight calf it's from his back," the Giants coach told reporters.
"He still played a really good role forward of the footy and we had to be mindful that he couldn't go at full tilt.
"We'll do everything (to get him up), he's our captain for a reason.
"He stayed so focused and played his role when we needed him.
"That decision will come down to Wednesday or Thursday, but we'll give him every opportunity to play.
"What gives me confidence is that he did play out the game, so we'll wait and see."
Whitfield had appendix surgery during the week and is the most likely of the trio to face the Tigers.
"He's a massive chance, he's a huge chance to play," Cameron said.
"If he's not fit or healthy enough to play 100 minutes then we won't pick him, but all signs are heading in the right direction.
"He's up and about and clearly he's an integral part of our team.
"He will train next week and look to play.
"The surgery was really simple, even though he had to have surgery, but every box was ticked and there were no setbacks.
"Lachie Whitfield will definitely be putting his hand up and if he gets there he gets there, but if he doesn't he doesn't."
Coniglio hasn't played since round 17 when he suffered a knee injury against Richmond that required surgery.
But Cameron said they will give him every opportunity to prove his fitness.
"We've always said that his best chance (to play again in 2019) would be if we made the last weekend (of the season) and now we've given him that chance," he said.
"We'll assess him during the week, but he did a really good session on Friday.
"It could be a big risk, but equally he is the heart and spirit (of our club).
"It's hard because you've got Brett Deledio (calf) who would love to play, and Callan Ward (knee) who has been whacking away for eight years at this footy club, and you'd love to pick him, but we can't.
"If 'Cogs' is right and we think that's the right decision then we'll go down that path."
Coniglio admitted himself he was unsure if he could get up for the huge clash.
"I actually don't know myself, but we'll see," the star Giant told AFL Media.
"Now that we're in I'll just have to do what I can to try and play."
GWS will be bolstered by the return of suspended star Toby Greene, who was sensationally hit with a one-match ban for making unnecessary contact to the face on Lions midfielder Lachie Neale a fortnight ago.
The Giants play off in their maiden grand final next Saturday against Richmond at the MCG at 2:30 (AEST).
