MIAMI -- Oklahoma City guard Shaun Livingston had surgery Tuesday to remove staples from an earlier procedure on his left knee.
"Everything went well," coach Scott Brooks said before the Thunder played the Heat in Miami. "It was minor surgery."
Brooks said there's no timetable for the return of Livingston, who has spent nearly three years trying to recover from tearing three ligaments in an ugly spill during a game in February 2007.
"He's going to be fine," Brooks said. "I haven't heard how many days or weeks, but they just said everything went well. They were pleased with what happened this morning."
Dr. James Andrews, who has worked on Livingston before, handled Tuesday's operation in Birmingham, Ala.
Pierce back at practice
WALTHAM, Mass. -- Boston Celtics forward Paul Pierce has returned to practice after missing a day with a sore left knee.
Pierce, 32, was hurt on Friday night against Atlanta. He says it was only a slight sprain, and he took part in the team's workout after missing Monday's practice. He says his return went smoothly.
Coach Doc Rivers gave him an occasional rest on the sideline.
Rivers and Pierce both say they expect the All-Star to be available against Golden State.
