Atlanta Hawks guard Lou Williams left Friday's game against the Brooklyn Nets due to a sprained right knee.
Williams' knee buckled during a fast-break opportunity in the second quarter. He was helped to the locker room by use of a wheelchair.
The Hawks later said Williams suffered a knee sprain and that he would undergo testing Friday night and when the team comes home.
Williams entered Friday's game as one of only three players on Atlanta's roster to have played in every game this season. He came into the contest averaging 14.5 points, which was third-best on the team.
