The injury occurred at the 2:47 mark of the second quarter Sunday of the Spurs-Houston Rockets preseason game. The team noted a timeline for his return would be determined later. As he was driving to the basket on a fast break, Murray went down and hit the floor, face down, as he put up a shot.
Murray tested his knee in front of the Spurs' bench before heading to the locker room with team officials. With Tony Parker now with the Charlotte Hornets, Murray is expected to be the full-time starter for San Antonio at the point guard position this season. Last year, Murray averaged 8.1 points, 2.9 assists and 5.7 rebounds in 81 games.
Head coach Gregg Popovich did not say who will take Murray's place in the starting lineup.
The ACL tear was later confirmed by another reporter, and shortly after that the Spurs themselves updated their injury report on Murray. He was named to the All-NBA defensive team last season.
