Dallas’ Van Horn leaves game with ankle injury

Van Horn left the game in the second quarter after landing awkwardly on his left leg while trying to secure a rebound.

He fell to the court in obvious pain and had to be helped to the locker room. His return to the game appeared doubtful.

Van Horn, who joined Dallas from Milwaukee in a trade earlier this season, had four points and one rebound for Dallas, which trails Houston 2-0 in the best- of-seven series.
