Melbourne midfield dynamo Jack Viney could make his AFL return to face Collingwood just two weeks after breaking his knuckle.
Melbourne will name Viney for Monday's Queen's Birthday clash, with the 22-year-old needing to pass a fitness test on Saturday to play.
"He's probably a 50:50 chance to play but we'll name him in the team and if he trains well Saturday and we haven't put him in we'll be kicking ourselves," Demons coach Paul Roos said.
"If you were a betting man, you'd bet that he's going to play."
The Demons are still uncertain when Christian Salem (thyroid issue) and Heritier Lumumba (concussion) will return to training.
Lumumba was due for another medical assessment on Thursday.
"Salo's (Salem) very much a medical issue and he needs to get on some medication and when the blood levels get to a certain level he can start upping his training, so it's a bit of an unknown," Roos said.
