Collingwood will make two changes ahead of the round three clash against St Kilda at the MCG on Saturday.

Jaidyn Stephenson will make his long-awaited return to the senior side after missing the opening two rounds of the season.

Coach Nathan Buckley credit the electric forwards value to the team in a press conference with the media on Thursday.

"He's (Stephenson) definitely in our best mix when he's up and about and I think he's ready to go so we should expect to see him run around on Saturday," Buckley said.

Unlucky to not feature yet this season, Rupert Wills will provide depth to the midfield with his work around the contest and physical strength.

"Rupe's done extremely well, his last month's been really strong. He was probably a little bit stiff to miss round one and was one of the players who came back in really good order off the isolation period,” Buckley said.

Brayden Maynard is set to play game 100 on Saturday, with the senior coach applauding his discipline since being drafted to the club in 2014.

"He's a great young man. You don't come in as a finished product and you've got to find different ways as you go along and I've been so impressed with his capacity to improve himself gradually and consistently as he's gone along his 100 games,” Buckley said.

"His teammates love him, we love his physicality, sometimes his elite skill gets overlooked, he's legitimately tough and he just loves playing for his teammates. He's one of the boys the rest of the group just loves to get around."

Collingwood's four emergencies are Jack Madgen, Josh Thomas, Mason Cox, Brayden Sier.

The first bounce at the MCG is set for 4.35pm. Tune in live on Fox Footy and on AFL Live Pass.
