New Jersey Nets center Brook Lopez underwent successful surgery on his right upper arm today, May 4, at the Hospital for Special Surgery in Manhattan, Nets General Manager Billy King announced.

The surgery, performed by Nets team orthopedic Dr. Riley Williams III and Dr. Andrew Weiland, involved the removal of bone mass and calcium deposits from Lopez’s right upper arm.

“Brook was bothered this year by a bony lump that developed after he was hit in the arm early this year,” said Dr. Williams. “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 will wear a sling for approximately one week and begin rehabilitation in two weeks. He is expected to fully participate in training camp for the 2011-12 NBA season.
