The team said Tuesday that the hard-throwing Zumaya fractured his right olecranon, which is the bony tip of the elbow right under the skin.
The injury was diagnosed Tuesday, one day after the injury left him writhing on the mound during a game in Minneapolis. He winced in obvious pain Monday night after throwing a pitch that Delmon Young fouled off with one out in the eighth inning of Detroit's 7-5 win over the Minnesota Twins.
Zumaya missed large chunks of the last two seasons because of shoulder problems.
The Tigers bought the contract of right-handed pitcher Casey Fien from Triple-A Toledo to take Zumaya's place on the roster. He was expected to join Detroit in Minneapolis for Tuesday night's game.
