BOSTON (AP) — Paul Pierce hit a go-ahead jumper with 31 seconds left and the Boston Celtics beat the Miami Heat 100-98 in double overtime Sunday after learning that All-Star point guard Rajon Rondo will miss the rest of the season with a knee injury.

Rondo will have surgery for a torn anterior cruciate ligament in his right knee. He was hurt late in Boston’s 123-112 loss, also in two overtimes, to the Atlanta Hawks on Friday night.
