Giannis Antetokounmpo was declared out for the remainder of the Bucks' 130-117 Game 1 loss to the Miami Heat on Sunday due to a lower back contusion, the team announced.
After the first-round game, Bucks head coach Mike Budenholzer stated that Antetokounmpo's X-ray came back "clear."
Kevin Love committed a charging penalty on Giannis Antetokounmpo with 1:40 remaining in the first quarter, causing Antetokounmpo to fall to the floor and land on his back.
After receiving his second foul in the first quarter, Antetokounmpo promptly left the court for the locker room.
Beginning the second quarter with tape wrapped around his lower back, he returned to the game with 9:56 remaining.
However, during his subsequent time on the court, Antetokounmpo did not attempt a shot and appeared to be hobbling while attempting to sprint up the court in transition.
At 8:33 of the second quarter, when Milwaukee committed a delay of game violation, Antetokounmpo checked out of the game and returned to the locker room.
