The left-hander said Wednesday that he likely won't pitch this season because he still has issues inside his surgically repaired shoulder.
All Mariners manager Don Wakamatsu will say is that doctors found inflammation in Bedard's shoulder in an MRI and are trying to determine what to do next.
The 31-year-old hasn't pitched since July 25, 2009. He had surgery Aug. 14 to repair a torn labrum.
He was set to return to Seattle's rotation earlier this month after a successful minor league rehabilitation stint. Then his shoulder began to ache again.
The Mariners signed Bedard to a $1.75 million, one-year deal before spring training, knowing he wouldn't pitch until summer at the earliest.
