The return of Dellin Betances has been interrupted for at least three weeks.
Relief from the Yankees will receive a cortisone injection Saturday to treat inflammation around a bony spine in the shoulder, said Friday evening managing director Brian Cashman.
Betances's right shoulder has been on the right shoulder since the Yankees signed it, Cashman said, but that has never been a problem.
The 31-year-old was recovering from a right shoulder injury in Tampa and had trouble playing during a simulated game on Thursday. He returned to New York on Friday for another MRI with a dye contrast, which revealed inflammation near the bony spine.
"It could have been a lot worse news," Cashman said.
The Betances will be closed for three weeks and Cashman said that he could run out six or seven weeks before he comes back for the Yankees.
