Jered Weaver left Monday's game against the New York Yankees after 12 pitches with a back injury. The Angels won anyway, defeating the Yankees for their seventh straight win, but after the game, the team ordered a battery of tests for Weaver.

From MLB.com:

... an MRI could reveal a bulging disk for Weaver.

"I can't really bend over too much," Weaver said. "Muscle relaxer's helping a little bit, but like I said, I've never had something like that happen before, so it was pretty painful. No doubt about it."

The Angels said they'll "most likely" call up a pitcher, regardless of whether Weaver needs to go on the DL. The team hasn't had a day off since May 10, and the bullpen had to absorb nine full innings on Tuesday. The three starting pitchers the Angels have on their 40-man roster are Garrett Richards, Trevor Bell, and Ariel Pena. Bell is struggling this season, and Pena is in AA, so Richards is probably the likeliest candidate.
