Phelps, 27, will be spending time on the disabled list and thus far the Yankees have not announced who will be taking his place in the rotation. Esmil Roger or Chase Whitley are candiates to replace him.
“It’s devastating,” said Phelps, who likely won’t be back in the rotation for at least three weeks in order to get his arm back into shape. “Like I said last night, this is one of the best stretches I’ve had in my career. Hopefully rest it, have it calm down, and come back and help this team get to the playoffs.”
Phelps is 5-5 with a 4.24 ERA in 26 games (17 starts) this season.
