CARLTON'S revival under interim coach John Barker has hit a hurdle with star midfielder Bryce Gibbs ruled out for the season after he suffered a serious pectoral injury against Richmond. 

Gibbs was scheduled to undergo surgery on Monday after tearing his left pectoral muscle during the third quarter of the Blues' loss to the Tigers. 

Carlton's head of football Andrew McKay said the surgery would ensure Gibbs made a full recovery.

"If we let Bryce's injury heal naturally, he would have still been out for up to eight weeks and could have risked further damage," McKay said.

"By having the procedure now it will ensure Bryce is fully recovered and ready to go for the start of the pre-season. 

"Obviously he is clearly disappointed that his season is over, but what this does do is give some of our younger players an opportunity to put their hand up for selection."

Gibbs' injury is not the only bad news for Carlton's midfield stocks, with Dennis Armfield set to miss a month after surgery to insert a plate to repair a broken right arm suffered against Richmond. 

In a more positive development, scans have cleared Michael Jamison of any further injury after he was subbed out against Richmond with concussion.
