Paul Pierce finished with 13 points and Rajon Rondo dished out 11 assists and collected nine rebounds, one night after his first triple-double of the season. Rondo had just seven points.
Thaddeus Young led Philadelphia with 22 points and Evan Turner scored 13. The 76ers have lost three of four.
Philadelphia won Friday when Turner hit the go-ahead basket in the lane with 3.9 seconds left in overtime and Rondo missed a game-ending shot after he slipped along the left baseline.
