Allen Iverson had a bounce in his step as he walked into the 76ers' locker room last night in Philadelphia. The obvious question was, "Are you playing?"

"Rock and roll," Iverson said.

And with that, the defending NBA scoring champion returned from a tumultuous stay on the injured list. His performance was equally dicey.

Playing for the first time in more than two weeks, Iverson tied his season-low with 11 points in the Sixers' worst loss of the season, 106-84, to the Hornets.

The 24-year-old Iverson was leading the league in scoring when he broke his right thumb against San Antonio Nov. 22.

The Sixers opened a roster spot for Iverson by placing reserve G Kevin Ollie on the injured list with tendinitis in the right knee.

UPDATE: Nets C Jayson Williams, who has been sidelined since breaking his right leg and injuring his knee April 1, hopes to start practicing after the New Year and return to the lineup in mid-January. Williams has had two surgeries since he was injured in a collision with teammate Stephon Marbury in a game against Atlanta on April 1.

SURGERY: Rockets F Charles Barkley, 36, underwent surgery to repair a severe knee injury that ended his basketball career Wednesday. Surgeons reattached the tendon that connects the quadriceps muscle to Barkley's left knee.
