Dodgers get positive report on Kemp's shoulder

PHOENIX -- The Dodgers received relatively good news Tuesday on the health of Matt Kemp, who went back on the 15-day disabled list Monday.

Kemp had an MRI exam on his sore left shoulder and was examined by Dr. Neal ElAttrache, who confirmed Friday's diagnosis that Kemp had irritated the acromioclavicular (AC) joint where the collarbone meets the shoulder.

ElAttrache said the injury is unrelated to the surgery he performed on Kemp last year to repair a torn labrum and a frayed rotator cuff.

Manager Don Mattingly said he's optimistic that Kemp, who received a cortisone injection Friday night, would be on the DL the minimum 15 days.

"I think so," Mattingly said. "But I don't want to go out on a limb. I think 15 and he'll be ready to go, but I didn't think he would be disabled."

Mattingly initially said he didn't think Kemp would need a rehab assignment, then backpedaled and said "possibly."

Kemp felt pain in the shoulder on a swing and miss Friday night against the Giants. Mattingly said Kemp also had discomfort in the AC joint in earlier this year and last year.
