Boston Celtics reserve forward Leon Powe will miss the remainder of the NBA playoffs because of a knee injury, The Boston Globe reported Tuesday. The Celtics already are playing without star forward Kevin Garnett, who likely will also miss the rest of the defending champions' playoff run. Boston and the Chicago Bulls are tied 1-1 in their first-round playoff match-up.

Paul Pierce delivered 21 of his 36 points in the fourth period and overtime Wednesday, pushing Boston to a 112-108 decision over Miami. The Celtics clinched the Atlantic Division title for the second straight year, although they continued to play without a significant segment of their roster. Ray Allen was out with an elbow injury, superstar Kevin Garnett missed his 13th consecutive game with a knee strain and Leon Powe did not play because of a sore knee. Pierce, however, carried the load again.

Leon Powe enjoyed a career-best effort Friday night in carrying the Boston Celtics to a 102-92 victory over Memphis. Powe scored 30 points, the highest total of his three NBA seasons, and grabbed 11 rebounds.
