Davis used both arms to come down hard on Smith as he drove to the basket. Initially called a common foul, officials reviewed the play and upgraded it to a Flagrant 2, which is an automatic ejection. Replays showed Davis' forearm catching Smith across the nose without much of an attempt to play the ball.
Smith got into a verbal exchange earlier in the period with Portland star Damian Lillard. The two were quickly separated by officials.
Portland led 82-60 at the time of the ejection.
