Young suffered the injury late in the third quarter and did not return. He collided with Hornets guard Gerald Henderson as the two ran toward the lane on a change of possession. Young's knee buckled, and he went down to the floor in agony. He had to be helped up and then limped to the locker room under his own power.
The team diagnosed Young with a hyperextended left knee at the time. X-rays were negative.
Young, 26, is averaging 13.6 points on 49.5 percent shooting in 18 games since being acquired by the Nets at the trade deadline.
