Jeremy Hefner has suffered a major setback in his return from Tommy John surgery.
PHILADELPHIA -- Jeremy Hefner's comeback from Tommy John surgery has hit a major snag.
Hefner was diagnosed in New York on Monday with a re-injury to a ligament in his right elbow as well as a stress fracture of the ulna bone. He may undergo reconstructive surgery again.
"Not good news on that front," assistant GM John Ricco said.
Hefner departed his sixth minor-league start last Wednesday after one inning. He was nearing a full return from Tommy John surgery, which was performed on Aug. 28, 2013.
Hefner wrote on Facebook about the ulna bone fracture: "Although this injury is extremely uncommon, it does happen. There aren't many case studies on it, but it does require me to have T.J. surgery again. Yes, that means starting completely over. I'm not sure what my course of action is. Should have a clearer picture in the coming days. I'm disappointed, but not shaken. I have a lot of things to be thankful for, and I'll rest in that."
