TEMPE, Ariz. (AP) Los Angeles Angels left-hander C.J. Wilson will be shut down for a few days with tendinitis in his throwing shoulder, a setback in his return from elbow surgery.

Wilson experienced pain in a Saturday bullpen session and underwent an MRI on Monday. Manager Mike Scioscia says he's relieved it wasn't something worse.

Wilson had bone spurs and chips removed from his elbow in August, the fourth procedure he's had on his left elbow. The 35-year-old Wilson says it's not unusual to have shoulder pain during the rehabilitation process.
