Jonathon Niese has been diagnosed with a partially torn rotator cuff, although surgery may be avoided according to assistant general manager John Ricco.
The diagnosis came after Niese was examined by team doctor David Altchek on Friday at the Hospital for Special Surgery in Manhattan.
Ricco said doctors believe the tear is small and surgery may not be needed if the injury can heal on its own after rest and rehabilitation. “But we’ll know more after a couple of weeks of rest,” Ricco said.
Niese missed a start earlier this month after he was found to have shoulder tendinitis. He was sent for a M.R.I. on May 30, which revealed no structural damage.
After skipping a start, Niese had two outings before Thursday’s, when he said he began to experience pain again. Ricco said the current tear occurred after that first test. “This is something that changed,” he said.
The Mets will now be without Niese for a month or longer. He was 3-6 record with 4.32 ERA this season.
