COLLINGWOOD has dropped Anzac Day medallist Paul Seedsman and also lost Jarryd Blair to an ankle injury for Sunday's clash with Greater Western Sydney at the MCG.

The Magpies will welcome back midfielder Taylor Adams, who missed Monday's clash against Melbourne with a toe injury, and ruckman Jarrod Witts who has been brought back in to contend with star Giant Shane Mumford.

Collingwood has named Brodie Grundy despite the ruckman being stretchered off the training track on Friday morning.

Grundy copped a head knock in a routine training drill and was taken to hospital as a precaution.

The results of his CT scan came back clear and the Magpies expect the ruckman to play, although football manager Neil Balme said a final decision would be made on Saturday.

Pacey defender Jonathon Marsh, who is yet to make his debut, has been included as an emergency.

Greater Western Sydney has made one change to the side that beat the Brisbane Lions by 30 points last weekend, with Nick Haynes replacing Aidan Corr in the 22.

Young Melbourne midfielder Alex Neal-Bullen, pick No.40 in last year's NAB AFL Draft, will make his AFL debut against St Kilda at Etihad Stadium on Sunday.

Key midfielder Dom Tyson makes his return from a medial knee ligament strain, while Jack Grimes, Viv Michie and Billy Stretch have also been included. 

Injured Demons Colin Garland (broken hand) and Aaron vandenBerg (hamstring) go out of the side, along with omitted trio Jack Fitzpatrick, Ben Newton and Matt Jones.

The Saints have made five changes, headlined by the return of veteran defender Sam Gilbert for his first game of the season.

Gilbert will play his first game since August last season due to a long layoff with a niggling foot injury, while Maverick Weller returns from a one-game suspension. 

Luke Dunstan, Tim Membrey and Darren Minchington are the other inclusions.

Jack Billings is out with shine soreness, while Cameron Shenton, Tom Hickey, Adam Schneider and Jack Sinclair have all been omitted. 

Schneider and Sinclair are back on the rookie list, after Daniel Markworth and Arryn Siposs returned to the primary list this week following shoulder injuries.
