Dr. Neal ElAttrache repaired the torn labrum and performed minor debridement of the rotator cuff in a one-hour operation at Kerlan-Jobe Clinic. Kemp will begin therapy in 7-10 days in Arizona.
The announcement indicated that Kemp would be ready for Opening Day, but did not say he would be at full strength when Spring Training begins in mid-February.
That means the Dodgers will have two of their three starting outfielders coming off major surgery -- Kemp and left fielder Carl Crawford, acquired with his $100 million contract from Boston, despite having August Tommy John surgery and still not fully recovered from wrist surgery.
Kemp suffered his injury slamming into the wall at Coors Field on Aug. 27. An MRI at the time revealed a frayed labrum, but the work done Friday revealed more damage than had originally been known.
Had it been a minor clean-up, Kemp had said he would have resumed baseball activities in four to six weeks.
If Kemp is not ready to start the season, the Dodgers could play Tony Gwynn in center field, or move right fielder Andre Ethier, who started last year's All-Star Game in center. Yasiel Puig, the $42 million Cuban signing, also could enter the picture. Shane Victorino is a free agent and is not expected to re-sign.
After missing 51 games earlier in the season with a strained left hamstring, Kemp insisted on playing through the shoulder pain and finish out the season.
Kemp was batting .337 at the time of the injury. After the crash, he hit .214 with six home runs, 15 RBIs and 33 strikeouts in 112 at-bats.
