Melbourne will name key pair Jesse Hogan and Christian Petracca and give them until match eve to prove their fitness for Sunday's AFL clash with St Kilda.
Hogan (ankle) wasn't sighted on Thursday at Demons training, where Petracca (finger) was also left out of any ball work.
Coach Simon Goodwin said that was always the plan for the next-gen stars, and they remained on track to play at Etihad Stadium.
"They trained strongly today in rehab and we're really confident they'll play this weekend ... we've still got a couple of days," Goodwin said.
"Internally and speaking to the players, we're confident that both will play."
Hogan has had knee trouble this year but it's ankle grief that had forced him to miss the Demons' main session for the week on Thursday.
"He rolled his ankle in the third quarter (against Essendon), so that's the bit we're making sure we get right. He had a knock to the knee as well but that's fine," his coach said.
Petracca missed Sunday's win over the Bombers after surgery on his infected finger.
The now-dissipated fear of an amputation shocked his senior coach.
"Clearly, when you get an infected finger and it gets to that point, you need to do something pretty serious. It can become a really serious injury," Goodwin said.
"As a club, we took the best (measure) possible to get it fixed as quick as we can to make sure that he misses a week but he gets back to play footy."
Co-captain Jack Viney was another welcome face at Melbourne training after missing the season to date with long-running foot issues.
Goodwin said he was firming to return for the round-eight trip to Brisbane to face Gold Coast.
"He was really strong at training today," Goodwin said.
"The plan has been to get him prepared to play AFL footy, similar to Tom McDonald last week."
