Texas Rangers pitcher Corey Kluber will be sitting out for four weeks due to a tear of the major muscle in his right shoulder, team officials said Monday.
Kluber, who played baseball at Coppell High School, left Sunday's game after his first inning as a Ranger "while experiencing tightness behind his right shoulder," officials said.
He was examined by a team doctor and underwent an MRI Sunday evening. He was diagnosed with a grade 2 tear of the teres major muscle in his right shoulder. No surgery is required.
Kluber will be placed on the injured reserves list.
He was acquired from Cleveland last December.
