CHICAGO (AP) -- Chicago Cubs left-hander Ted Lilly has had surgery on his left shoulder.

The Cubs said the arthroscopy and debridement procedure performed Monday by Dr. Lewis Yocum in Los Angeles revealed no major damage.

The Cubs said they will determine after the first of the year a timetable for Lilly to start a throwing program.

Lilly was 12-9 with a 3.10 ERA in 27 starts last season.
