Brook Lopez has surgery on arm

New Jersey Nets center Brook Lopez underwent surgery on his right arm at the Hospital for Special Surgery in Manhattan on Wednesday.

Nets team orthopedist Dr. Riley Williams III and Dr. Andrew Weiland removed a bone mass and calcium deposits from Lopez's right upper arm, Nets general manager Billy King announced.

"Brook was bothered this year by a bony lump that developed after he was hit in the arm early this year," Williams said in a statement released by the team. "The mass was successfully removed today. A full recovery is expected, and Brook should be able to return to basketball activities in approximately six weeks."

Lopez played through the problem this year and has not missed a game in his three-year career. He averaged 20.4 points and 6.0 rebounds per game for the Nets.

He is expected to start rehabilitation in two weeks and be ready for training camp.
