Team officials said X-rays were negative and he will be re-evaluated Thursday.
The injury occurred late in the third quarter when Young collided with Gerald Henderson in the lane after a sudden change of possession.
He remained on the floor for about a minute as teammates gathered around before getting up and walking off the floor with a noticeable limp. He went straight to the locker room.
Young had 11 points on 5-of-12 shooting.
