The New York Yankees will be without Corey Kluber for at least two months because of a right shoulder injury.

Kluber was pulled after three innings Tuesday against the Toronto Blue Jays. He tossed a no-hitter last week.

An MRI on his ailing shoulder revealed a subscapularis strain, which is expected to keep Kluber from throwing for at least four weeks, followed by at least four weeks of rehabilitation.

Aaron Boone said he doesn't believe the no-hitter caused Kluber's injury. Kluber called the whole situation "frustrating" Tuesday, saying he felt some tightness in the shoulder warming up, but it's unclear what caused the injury.
