– Angels lefthander C.J. Wilson said he likely will require surgery and miss the rest of the season after an MRI revealed bone spurs on all sides of his pitching elbow.

"There's nothing much I can really do," Wilson said. "I don't have a good knuckleball."

Angels manager Mike Scioscia said it was obvious from Wilson's four-inning, six-run start on Tuesday that he was struggling.

Wilson has dealt with bone spurs for much of his career. He had a similar surgery in 2008 and 2012 and recovered well.

In 2013, he went 17-7 with a 3.39 ERA.

The loss of Wilson should not jolt the Angels significantly. Righthander Jered Weaver is expected to return from a hip injury this week. The team should need a replacement starter only once, on Sunday.
