DETROIT (AP) — Tigers closer Joe Nathan will miss the rest of the season with a torn ligament in his pitching elbow.

Nathan tore his ulnar collateral ligament on Wednesday while pitching on a minor-league rehabilitation assignment with Triple-A Toledo. Hoping to show he was ready to come off the disabled list, he tore both his previously strained flexor pronator and his UCL.

Detroit manager Brad Ausmus made the announcement Thursday, and Nathan was expected to talk to reporters later in the day.

The 40-year-old is a six-time All-Star, but is coming off one of the worst seasons of his career — he had a 4.84 ERA in 2014 and blew seven saves.
