Collingwood is set to blood its seventh debutant of the season with midfielder Trent Bianco to pull on the black and white against Geelong on Saturday afternoon.

A knee injury hampered Bianco's pre-season, but in recent weeks has impressed at VFL level, averaging 26 disposals, 7.5 tackles and a goal.

Bianco is known to be a creative playmaker with elite decision making and execution by both hand and foot on both sides of his body.

Nathan Murphy makes his way back into the line-up, while Brayden Sier earns a spot in the 22 after being on the cusp of selection for a number of weeks and defender Jack Madgen returns after sitting out round 10.

All Australian defender Darcy Moore will run out for his 100th game. 

Taylor Adams comes out of the line-up as he battles knee soreness, while Tyler Brown (shoulder) and Josh Thomas (ankle) have not been able to get up for round 11. As reported earlier in the week, Beau McCreery was ruled out with a minor calf strain.

Our emergencies are Mark Keane, Will Kelly, Finlay Macrae and Jay Rantall. The medical substitute will be determined one hour before the match starts.

Don't miss the action on Fox Footy from 1.45pm (AEST).
