Scans have confirmed that Ryan Crowley has torn his pectoral muscle during a training session at Fremantle Oval.

The 2012 Doig Medallist will have an adjusted training program for six weeks, however he will not have to undergo surgery.

Senior coach Ross Lyon was confident the injury would not hinder the 28-year-old’s 2013 season.

“We expect Ryan to be able to maintain his fitness and be available for selection come round 1 of the season proper,” Lyon said.
