Nets guard Jarrett Jack left Saturday's game against the Celtics in the third quarter with right knee sprain (Jan. 2).
Driving down court on a fastbreak, Jack slipped on the court after he tried to control a bounce pass from Wayne Ellington and went down, grabbing his right leg. He was helped off the court and taken to the locker room.
In 22:48, Jack recorded nine assists and scored just two points on 0-for-5 shooting.
He has averaged 13.2 points, 7.3 assists and 4.4 rebounds in 31 games with Brooklyn this season.
