The oft-injured left-hander had been pitching for the Dodgers at Class-A Rancho Cucamonga, rehabbing a strained lat muscle. The news was announced Thursday.
The 36-year-old Bedard, from Ottawa, went 71-82 with one save in a big league career that included time with Baltimore, Seattle, Boston and Tampa Bay. His best season came with the Orioles in 2007, when he went 13-5 with 221 strikeouts and finished fifth in the AL Cy Young Award voting. He was 15-11 a year earlier.
But he only topped 150 innings once after 2007 because of a series of injuries in 2013.
Bedard made three starts for the Los Angeles Dodgers minor league team in the California League this season. He had been slowed by injuries late in his career.
