Milwaukee Bucks star Damian Lillard exited in the first quarter of Sunday night’s Game 4 against the Indiana Pacers with a left lower leg injury.

The team ruled him out for the game shortly after.

Lillard was injured while trying to help secure an offensive rebound midway through the first quarter. After tapping the ball away from a Pacers player, Lillard hit the ground and grabbed his left leg, remaining down for the next defensive possession.

He hobbled to his right foot at the next dead ball and needed help getting off the court while not putting any weight on his left leg. He was escorted to the locker room immediately.

Lillard had missed the team’s final 14 regular-season games with deep vein thrombosis in his right leg, but he returned in Game 2 of the first-round series against the Pacers after a month out of action in a recovery the team called unprecedented.

However, Lillard had not been able to match his usual production so far in the series, averaging 10.5 points and 6.0 assists on 24% shooting (6 of 25) in the first two games. He missed his only two shots in Game 4 before exiting.

Milwaukee currently trails 2-1 in the series against Indiana.
