Collingwood could make up to five changes to its team to take on Melbourne at the MCG on Sunday.

The five inclusions include one debutant, but he’s certainly not your typical first gamer.

American ruckman Mason Cox has been promoted off the rookie list in place of the injured Matthew Scharenberg.

Standing at 211cm, Cox has played 20 VFL games since arriving at the club at the tail end of 2014.

He played two NAB Challenge matches earlier this year, serving notice with two goals against Geelong in the series opener.

While his size allows him to contribute as a ruckman, Cox has impressed as a forward in the VFL, where his size makes him a difficult proposition for any defender.

Cox is no guarantee to play this week, having been named on an extended interchange bench. If named as an emergency, he will line up in the VFL on Sunday.

At the other end of the spectrum of experience are the four remaining inclusions.

Steele Sidebottom returns from suspension, Travis Varcoe is back after a three-week layoff with a hamstring strain and premiership pair Alan Toovey and Brent Macaffer are back after impressing in the VFL.

The quartet bring with them 530 games of experience to a team that was the youngest to run out on an AFL ground in round three.

The two players ruled out are defenders Marley Williams (foot) and Brayden Maynard (hamstring).

Sunday’s 25-man squad will be trimmed to 22 at 5pm on Friday.
