Bradley undergoes right shoulder surgery

Celtics guard Avery Bradley underwent surgery on his right shoulder Tuesday at New England Baptist Hospital, the second of two procedures aimed at getting him back to full health next season.

Bradley originally had left-shoulder surgery in May, ending his season during the Celtics' playoff run. With that sufficiently healed, he underwent a stabilization procedure on his right side on Tuesday with team physician Dr. Brian McKeon.

The team did not announce a timetable for his return to action.

Earlier this week, Celtics director of player personnel Austin Ainge was not optimistic that Bradley would be ready for the start of the 2012-13 season, which, combined with the departure of Ray Allen, leaves the team searching for depth at shooting guard this offseason.

Bradley elevated to a starting role during his second NBA season and averaged 7.6 points, 1.8 rebounds, and 1.4 assists over 21.4 minutes per game in 64 appearances (28 starts) last season.
