Collingwood has held its main training session for the week at Gosch's Paddock this morning.

All eyes were on Simon Prestigiacomo, as he tries to prove he's over his calf injury.

He trained with the main group, and appears certain to return for next Friday night's preliminary final.

Doubt still lingers over the fitness of Sharrod Wellingham, who was a no-show at training, still struggling with his ankle injury.
