The Celtics announced on Sunday that Rajon Rondo injured his right knee in the fourth quarter of Boston's double-overtime game with the Hawks on Friday. In the video above, you can see the play during which it is believed Rondo suffered a torn ACL.
Rondo lands awkwardly after making a pass and then can be seen favoring his right leg as he hops on one foot in the few seconds following the play.
Rondo stayed in the game and played in both overtimes in Atlanta. It wasn't until after he underwent an MRI on Sunday afternoon during the Celtics-Heat game that Rondo realized he had torn his ACL.
