Conor McGregor didn’t exactly receive a warm welcome from Miami Heat fans on Friday night.

The 34-year-old left-hander was on the court for the game and, at halftime, announced that his TIDL Sport body spray is now an official sponsor of the team.

Despite that though, he was booed by the Miami faithful, but it may have been for a good reason.

During the announcement, Heat mascot Burnie approached the UFC legend with boxing gloves.

But Burnie was no match.

McGregor landed a vicious left hook that sent the mascot to the ground.

Burnie was then dragged off the court by members of the Heat game entertainment crew.

Overall, it was not a good night for the Heat, as they lost Game 4 of the NBA Finals, 108-95, to the Denver Nuggets.

Denver is now one win away from its first NBA title in franchise history.

Ironically, if the Heat come back to win the series, they’ll be only the second team to the Finals, joining the Cavs team, and the first to do so in any playoff series since the team they’re trying to come back against. He did it twice in 2020.
