Hawks second-year guard Trae Young left Friday night's game against the Bucks with a right ankle sprain and did not return, the team announced.
An x-ray taken after the game Friday came back negative, the team said, but Young will remain in Atlanta while the team travels to Chicago.
The injury occurred late in the second quarter when Young appeared to slip in the paint after picking up his dribble. He fell awkwardly and had to be helped off the floor.
Young is in the middle of an All-Star caliber season. Despite Atlanta's struggles, the Oklahoma product will likely be among the 2019-20 Eastern Conference All-Stars. He entered Friday averaging 29 points and 8.5 assists per game, while shooting 44% from the field. The Hawks, however, have only six wins.
Atlanta trailed by 23 points at halftime and went on to lose 112-86.
