One of the referees had to take himself out of the Spurs-Grizzlies game on Tuesday night after injuring his leg in the first quarter.
As Memphis' Tony Allen sprinted down the court on a fast break, he didn't realize how close he was to officoal Tommy Nunez Jr. Just before he caught the ball on a long pass, Allen appeared to accidentally trip Nunez and the referee fell to the floor.
Nunez laid on the ground by the Spurs bench for a moment as the San Antonio coaches tried to help him. He left the game at the next time out. Scroll down to watch the video.
