AFTER two agonising years battling a serious foot injury, Jack Trengove is "creeping closer" to a senior return but will be made to wait at least another week to make his long-awaited comeback, Melbourne coach Paul Roos says.

The former co-captain hasn't played AFL since round two, 2014 but after seven impressive matches in the VFL this season, Trengove has told Roos he is ready to be considered by the Demons.

However, the Dees will resist the temptation to bring the 24-year-old straight in for a crunch clash against Port Adelaide at Traeger Park in Alice Springs.

"I spoke to (Trengove) again today. He's not too far (away). He's going really, really well. He's not going to play this week," Roos said.

"You're probably factoring in the travel, the team going well last week, things like that. 

"We want to give Jack a chance, when he does play, to be able to play really well. 

"He's creeping closer, but it's not going to be this weekend." 

The Dees will make two changes to the side that thumped the Brisbane Lions, with Dom Tyson (illness) and Neville Jetta (suspension) set to return. 

Young gun Clayton Oliver (corked quad) walked laps at a wet training session on Thursday and has already been ruled out, with Melbourne yet to decide who else will make way.
