Melbourne co-captain Jack Viney could be some distance off returning from a foot injury.
Viney played through foot issues in the back half of 2017, with an operation on his plantar fascia after round 15 and a stress fracture soon after that keeping him to just 18 games.
The stress fracture has kept him from Melbourne's pre-season, admitting he won't be right for their pre-season camp later this month.
"Hopefully around the Maroochydore camp I'll be doing some solid running," Viney told melbournefc.com.au.
"I'm probably not into the main group by then but if I can get a really solid block of conditioning in during that time then hopefully I'm back into some contact and doing some drills with the team around early February."
Viney hopes to be back at full training in February, but admits there is an unknown about when he will be back.
"I'm really not sure what timeframe I'm looking at being back with the main group. For me it is still really at the stage where it's session by session," he said.
"If I feel comfortable doing what I did then we progress it. Some sessions we might have to hold [back] if it doesn't feel quite right.
"That's pretty much where I'm at."
The 23-year-old wants to be right for Melbourne's round one game against Geelong - particularly against Patrick Dangerfield, Joel Selwood and Gary Ablett - but getting over the injury is his first priority.
"Geelong has got a pretty stacked midfield, which as a competitor you like to go up against and challenge yourself," he said.
"I'm pretty excited about that but we'll try to get there first."
