Pittsburgh, PA (SportsNetwork.com) - Miami Marlins reliever Kevin Gregg will have season-ending surgery to remove bone chips from his right elbow.
Gregg, 36, appeared in just 12 games for the Marlins this season, allowing 10 runs in nine innings of work out of the bullpen.
The 12-year veteran has compiled a 30-44 record with 177 saves and a 4.15 ERA in stints with the Angels, Cubs, Blue Jays, Orioles and Marlins.
In addition, Jarred Cosart has been scratched from his scheduled start on Thursday against Pittsburgh due to left oblique soreness. The injury is not serious and Cosart should be ready to make his next start.
Left-hander Brian Flynn will take the mound in place of Cosart opposite of Edinson Volquez in the series finale against the Pirates on Thursday.
Cosart gave up four runs on four hits and two walks over 5 1/3 innings against the Reds on Friday in his Marlins debut.
