Geelong's main training session looms as crunch time for Max Holmes as the young gun attempts to prove his fitness from a hamstring injury for the AFL grand final.
Sydney ruck-forward Sam Reid also had a scan on Monday as he tries to recover in time from an adductor injury.
Holmes was substituted out of the Cats' preliminary-final thumping of Brisbane last Friday night and appeared devastated as he lay face down on the sidelines.
But he was later cleared of a serious hamstring injury, with the Cats' medical staff and Holmes optimistic about his prospects this week.
Holmes trained away from the main group during Monday's open training session at GMHBA Stadium.
The young Cat carefully went through some exercises before moving on to running laps, to the delight of the big crowd.
The light intensity of Monday's session means Wednesday's main training shapes as Geelong's decision day on Holmes' availability.
Star teammate Patrick Dangerfield is growing more hopeful that Holmes will be ready for the grand final.
"A lot more (chance of getting up) than I did post-game, I think that's for everyone," Dangerfield told reporters.
"It'll obviously be left to the last minute.
"We've got wonderful medical staff and they'll make the best call for everyone involved, but he's shocked a few of us."
Meanwhile, Sydney co-captain Dan Rampe said they also remained unsure about Reid's availability.
Reid was subbed out at the start of the second half of Saturday night's one-point preliminary final win over Collingwood at the SCG.
"He's been in for a scan this afternoon. We've just had our team meeting and fingers crossed for him," he said.
"He's an important part, obviously he's been in unbelievable form and he'll get every opportunity - he's not one you're going to rule out early."
Reid has proved valuable as a forward who can support Tom Hickey in the ruck.
"I don't want him to miss, he's a good mate of mine, our little boys are good mates too, so I'd love for him to get up," Hickey said.
"He's maybe in a good position that he's been injured a fair bit through his career so he knows how to handle it and not get too emotional.
"But he'll be as driven as anyone to get himself right."
Hayden McLean and Joel Amartey shape as potential replacements if Reid is ruled out, with Peter Ladhams still suspended
