Of the six non-roster pitchers still in camp, Bedard is the only starter, although Chad Gaudin was a successful starter earlier in his career.
Bedard said he had a similar injury earlier in his career that sidelined him for about three weeks.
Bedard went 4-6 with a 4.76 ERA last season with Tampa Bay until being released in August. He is 71-82 with a 3.99 ERA over 11 seasons in the big leagues.
