Conor McGregor leveled Miami Heat's mascot just before the Denver Nuggets leveled the Miami Heat in Game 4 of the NBA finals

• The Miami Heat lost Game 4 of the NBA Finals to the Denver Nuggets on Friday.
• The Miami Heat's mascot also lost a playful bout with UFC champion Conor McGregor.
• McGregor landed a punch hard enough to send the man playing the mascot to the hospital.

The Miami Heat took a beating Friday night. And so did the team's mascot.

The Miami Heat lost to the Denver Nuggets in Game 4 of the NBA Finals, falling to a 1-3 deficit in the best-of-seven series.

But the real drama came in the first half when UFC champion Conor McGregor took the floor to promote his new pain-relieving spray.

McGregor play-fought Miami Heat's mascot, Burnie (get it?), pretending to knock Burnie out. Burnie was then dragged off the court as McGregor sprayed him with his pain reliever.

It seems the bit went a little too far, however, according to a report by The Athletic.

McGregor apparently landed one of his punches a little too realistically, sending the man performing as the mascot to the emergency room, where presumably he got some pain medication not sponsored by the Irish mixed martial artist.

Reporters at the Irish Mirror tried McGregor's pain spray and had some very strong opinions if you're interested.

And here's a video of the bout, McGregor's first fight in three years:
