Angel reliever John Dopson has been diagnosed with a bone spur in his right elbow. If he feels the spur confines him, he will undergo arthroscopic surgery.
The Angels still will have to make room for Langston this week, but Dopson needs surgery, the team will place him on the disabled list and keep relievers Bill Sampen and Scott Lewis.
Dopson is tentatively scheduled to start Wednesday against Texas, Rodgers said.
Angel first baseman Eduardo Perez underwent a magnetic resonance imaging test on strained ligament of his left hand. He suffered the injury April 26 in New York, and his hand has not healed. Perez has been told not to pick up a bat until at least Monday. Team officials hope the swelling will subside during the layoff.
Angel reliever Mike Butcher figured he'd be back from his minor-league stint in 10 days. He was wrong. It took 12.
Butcher, who was demoted April 23 to the Angels' triple-A Vancouver team with a 16.62 ERA, returns after having been successful in all five of his save opportunities, for a 1.59 ERA.
"I feel a lot better about myself now," Butcher said. "I was in control of myself down there. And I wasn't in control here. I was just frustrated.
"I want to be myself again, and I know I will."
