Midfielder Sharrod Wellingham will return back into the side for the injured Dale Thomas.
Thomas will miss the clash with an injury to his upper-calf which has resulted in swelling behind the knee. The team is hopeful to have the small forward back for the round 22 game against Fremantle in Perth.
Shannon Cox, Rhyce Shaw, and Simon Prestigiacomo have been listed as emergencies.
Wellingham will play his 11th game of the year and his first against Sydney.
Collingwood will be looking to win its third consecutive game to cement its spot in the eight. This will be the Magpies' fourth game at the Dome this year, with a record of one win and two losses.
