Collingwood says Alan Didak will still play a "significant" role in the season despite tearing his troublesome adductor muscle yesterday.

The Magpies said Didak had suffered a complete tear of the muscle, in the upper leg near the groin, in the opening minute of the match against Melbourne. But they said the fully torn muscle would heal and would not require surgery.

Didak missed two months as a result a partial tear to the adductor in the pre-season and yesterday was only his fifth game of 2012. Yesterday's injury took place when he was kicking at goal.

Collingwood's director of football, Geoff Walsh, said the full tear would help Didak to recover in the short to medium term.

“Alan previously had a partial tear that was a consequence of the injury he suffered in the pre-season. With the muscle being completely torn away it will allow a full attachment to take place that will not require surgery,” Walsh said.

“The advice is that the healing and rehabilitation process will not keep Alan sidelined for as long as he was in the pre-season. It's very much a short to medium term injury.”

In a statement, the club said "fears of the injury being season-ending have been dispelled".

“Alan will go into a recovery phase and then a strengthening phase, to build back up his strength and fitness, and we're confident that he won't be out for as long as he was last time.”

"These things can rarely be predicted with exact precision but we're expecting Alan to play a significant role in the season.”

Didak was jeered by some Demons as he hobbled from the field - a response that Collingwood coach Nathan Buckley said was disappointing.
