Celtics' Rivers ejected after arguing call

BOSTON -- Boston Celtics coach Doc Rivers has been ejected from Monday night's game against the Atlanta Hawks.

Rivers drew two quick technical fouls arguing a flagrant foul call on Glen Davis in the third quarter.

Assistant coach Armond Hill took over for him -- and then drew a technical of his own.

The Celtics led 67-57 with 6:16 left in the third quarter when Davis rode Marvin Williams away from the basket on a fast break.

Jamal Crawford made three free throws, then Williams hit one of two for the original foul to cut the deficit to six points, and then the Hawks got the ball out of bounds.
