Boston Celtics star point guard Rajon Rondo has torn his anterior cruciate ligament and will miss the rest of the season.

The team made the announcement during Sunday’s game against the Miami Heat. The Celtics had lost six in a row heading into the nationally televised game despite back-to-back triple-doubles by the point guard who had been elected to start for the East in the Feb. 17 All-Star game in Houston.

Rondo injured his knee in Friday night’s double-overtime loss in Atlanta, a game in which the Celtics blew a 27-point lead. He reported to the TD Garden on Sunday for a pregame shootaround but was taken to a hospital after complaining of knee pain.
