Chris Young has a torn anterior capsule in his right shoulder, the same injury that sent Johan Santana to the operating table in September.

Young has not resolved to have surgery, assistant GM John Ricco said. Either way, it is hard to imagine Young contributing again this season. Young had the same issue last year, according to Ricco, and opted for rehab rather than surgery.

"Not the news we were looking for," Ricco said.

Meanwhile, Dr. James Andrews concurred with the original diagnosis from team doctor David Altchek that pitching prospect Jenrry Mejia needs Tommy John surgery. Altchek will perform that procedure, Ricco said.

Young was examined by Altchek in New York on Monday, a day after undergoing an MRI exam and two days after he was scratched from his scheduled start against the Los Angeles Dodgers.

Santana underwent Sept. 14 for the injury and is only now nearly due to step on a mound for the first time, with an eye toward a July return to the majors.

"Right now they haven't determined the course of treatment," Ricco said. "The two options are surgery or rehab, and over the next couple of days they'll decide which route to go."

Ricco said the explanation for Young feeling pain in the back of his shoulder when the tear is in the front is because the tear created looseness and movement of the shoulder.

The news cements Dillon Gee in the rotation as Young's replacement.
