Texas Rangers pitcher Corey Kluber will be "shut down from throwing for a minimum of 4 weeks" after an MRI determined he had a grade 2 tear in his right shoulder, the team announced Monday.
He will be placed on the injured list Monday.
Kluber was pulled from his first start with the Rangers after just one inning Sunday. In his Texas debut, the two-time Cy Young winner struck out one and walked one against the Colorado Rockies before exiting with tightness in the back of right shoulder.
The team wanted to further evaluate the 34-year-old before determining his status moving forward, but now it's clear he will miss more time.
