Jon Niese has a partial tear of his rotator cuff, assistant GM John Ricco said Friday.
Niese will be reevaluated after two weeks of rest, after which it will be more clear if he needs surgery.
The tear is a new injury, Ricco said; the MRI he had a few weeks ago, when he missed a start due to shoulder tendinitis, showed no damage.
Greg Burke will take Niese’s place on the active roster as the Mets shift back to a five-man rotation.

Shoulder injuries — especially to the rotator cuff — are not easy to come back from for any pitcher.
This is a big blow for the Mets. Niese is a huge part of their future rotation and was meant to serve as an experienced anchor for the young pitching now arriving in the big leagues. Hopefully an extended period of rest helps Niese, but any tear — no matter how small — is never a good thing. Niese’s status for the remainder of the season has to be up in the air, and now the Mets have to figure out a way to address this hole in the rotation in the short-term… and potentially the long-term, as well.
