Atlanta Hawks forward Marvin Williams has undergone minor surgery on his lower back to alleviate the pain from a bulging disc.

The outpatient procedure was performed Wednesday at Peachtree Orthopedic Clinics in Atlanta. The team says Williams walked out of the facility on his own and should be able to resume full basketball activities in six to eight weeks.

Williams was slowed by back problems in 2008-09. This season, he missed 11 games after landing hard on his back attempting to make a steal in December game against Golden State.

The 24-year-old averaged 10.4 points and 4.8 rebounds while playing less than 29 minutes a game, the lowest total since his rookie season.
