The 40-minute arthroscopy was performed by team physician Dr. Neal ElAttrache after a new area of cartilage damage was discovered and debrided. Elbert had arthroscopic surgery on the same elbow Sept. 19, ending his 2012 season. He will start his physical therapy in three days and a throwing program in six weeks.
Elbert went 1-1 with a 2.20 ERA in 43 relief appearances last season.

In a crowded Dodgers bullpen, at least two players' chances of making the opening-day roster just improved.
Left-hander Paco Rodriguez allowed one run in 11 appearances over 6
