Travis Varcoe is in a race to be fit for Geelong's Round 23 clash against Sydney as the club tries to determine the extent of his latest foot injury.
The exciting forward suffered the injury during the first quarter of the Cats' 34-point win over the Western Bulldogs on Sunday.
He was unable to train on Tuesday morning and will spend the next two days in a moon boot as a precaution to ensure he will be fit for the Cats' finals campaign.
"We're still a little unsure, except we know it's not very bad news," Geelong coach Chris Scott said.
"We're going to be really cautious with it over the next couple of days. He's had some preliminary scans that look quite good - certainly not a recurrence of an old injury. But we need to see the extent of the new injury, if there is anything significant there, which we don't think there is.
"Best case scenario: he'll be fine this week. Worst case: it might be a week or two."
The Geelong coach admitted the club took a risk in selecting Varcoe against the Western Bulldogs, but conceded they would do the same again this week if he was fit.
"It's not ideal but we were prepared to take a little bit of a risk bringing him back to get him ready for finals last week and I dare say that we'd be prepared to take that risk again this week," he said.
Meanwhile, youngster Billie Smedts will certainly miss the clash against the Swans with a broken finger.
The 20-year-old suffered the injury after coming into the game against the Bulldogs as the substitute for Varcoe and underwent surgery on Monday.
"The initial conversation I've had with him has been quite positive," Scott said.
"He's going to be pushing to make himself available for the finals series.
"But it's just a really difficult one to comment on until he starts to get some movement back in that hand, and that certainly won't be for a week."
In better injury news, the reigning premiers are hopeful young ruckman Nathan Vardy will make his AFL comeback against the Swans after missing the whole season with hip problems.
The 21-year-old returned to the VFL earlier this month and played well against Williamstown last weekend, recording 36 hit-outs in an impressive display.
"Vards has done really well," Geelong physio Mike Snelling told the Geelong website on Tuesday.
"Things are going great for him. We'll keep training him this week and hopefully he'll come up this weekend."
Fellow ruckman Orren Stephenson is also a chance to be selected after recovering well from the hand he broke against West Coast in Round 20.
"Orren has progressed well," Snelling said.
"We anticipate him to be out there training (on Wednesday). We'll see how he handles the ball and hopefully he'll be available on the weekend."
The Cats will also welcome back Joel Selwood, Matthew Scarlett and Taylor Hunt for the game against the Swans after the trio were rested last weekend.
