WALTHAM, Mass. (AP) -- Boston Celtics forward Paul Pierce has returned to practice after missing a day with a sore left knee.

Pierce was hurt on Friday night against Atlanta. The 32-year-old 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 him to be available against Golden State on Wednesday.

Rivers also says guard Tony Allen is moving well but might not be ready to return. Allen has yet to play this season after offseason knee surgery.

The Celtics are 8-3 but have lost two games in a row.
