NEW YORK (WFAN/AP) – Joba Chamberlain’s dye contrast MRI has revealed a torn elbow ligament and the pitcher will likely need Tommy John surgery, ending his season.

The Yankees announced the injury before Thursday night’s game against Boston. A test earlier in the day revealed the tear.

New York put Chamberlain on the 15-day disabled list Wednesday with a stiff elbow. Chamberlain and the Yankees said they were stunned when the exam showed the severity of the injury.

Yankees manager Joe Girardi joined Mike Francesa on Thursday to talk about the injury.

“We had no idea,” Girardi said, “he had none of those symptoms” of a torn MRI.

When asked about the possibly of Phil Hughes replacing Chamberlain in the bullpen upon his return from the DL, Girardi said that move was unlikely.

Instead “you might see some young kids get called up.”
