Bucks coach Joe Prunty did not have an official update on Antetokounmpo's injury postgame.
Antetokounmpo appeared to get hurt in the second quarter when he tripped over teammate Shabazz Muhammad under Milwaukee's basket. He stayed in the game for a brief period, but hobbled around the court while grimacing. He went to the locker room with about four minutes remaining in the second quarter and did not return.
The team downgraded him to out at halftime.
He's averaging 27.5 points and 10.1 rebounds this season for Milwaukee, which is eighth in the Eastern Conference. He had 12 points before leaving.
