Kelley's rehab put on hold after lower back setback

CHICAGO -- Yankees reliever Shawn Kelley, currently on the 15-day disabled list with a stiff lower back, sustained a setback after playing catch this week and has had his rehab put on hold.

Kelley played catch on Monday at Yankee Stadium, according to manager Joe Girardi, and woke up feeling stiff on Tuesday.

"The catch is on hold, the side will be on hold for a little, and obviously the rehab game that we were planning is on hold," Girardi said. "We just have to wait and see."

The Yankees were hoping to have Kelley pitch in a Minor League rehab game this weekend, but those plans have been scrapped. Girardi said that Kelley was sent for more tests, but they came back clean.

"He's just having some muscular issues back there, it seems to be," Girardi said. "There's no disc problems; at least from the MRI we haven't had any."
