Boston's Isaiah Thomas turned the ball over with four seconds left in the game, Phoenix Suns rookie Tyler Ulis picked up the ball and drained a three-pointer at the buzzer to stun the Celtics 109-106 Sunday evening.

Thomas scored 35 points but missed a free throw with 11-seconds left that would have put the C's up three.

Instead, Erice Bledsoe came down the floor and tied the game with a layup and then the turnover to Ulis.

The Celtics fall to 40-23 and a game in LA against the Clippers Monday night.
