SECOND UPDATE, 5:02 PM -
Mets assistant general manager John Ricco just announced that Jonathon Niese has a partial tear of his rotator cuff. Ricco stated that Niese would rest for two weeks before receiving another MRI. Per Ricco, the Mets don’t expect that Niese will need surgery since he doesn’t have a “significant tear.”
I’m not sure what kind of information Terry Collins had when he stated Niese would likely be back in about three weeks. It’s safe to say, though, that he wasn’t aware of the severity of the injury.
UPDATE, 4:21 PM -
Per the beat writers, manager Terry Collins termed Niese’s injury “nothing severe.” Collins further noted that Niese will rest for a few days before starting rehab, while referring to the injury as a “strain.” Niese had been pitching through various maladies this season before hitting the DL.
In 14 starts this season, Niese, 26, is 3-6 with a 4.32 ERA and 1.61 WHIP. He’s allowed 91 hits in 77 innings, while walking 33 and striking out 49. It’s highly likely that Niese’s injuries had a negative impact on his performance. Hopefully he rounds back into form after he gets healthy and is activated.
As far as a timetable for Niese’s return:
Terry Collins estimated 3 weeks for Jon Niese return to MLB. Will probably need one rehab start. #mets

Niese left last night’s game in the fourth inning with an apparent left shoulder injury. Rubin noted that the Mets have yet to announce what Niese’s official diagnosis is.
With Niese now on the disabled list, the Mets’ conundrum (who to remove from the starting rotation) has been rendered moot. Since the Mets are going with a five man rotation starting today, Zack Wheeler‘s home debut will likely be Sunday, June 30th against Washington.
