The bell rang, and Curtis Harper left.
One second into his fight with Efe Ajaba at The Armory in Minneapolis on Friday night, the heavyweight left the ring and walked back up the aisle, exiting the arena.
The spectacle was a bizarre diversion on an otherwise successful night of boxing in downtown Minneapolis, which was broadcast nationally on FOX Sports 1.
According to Premier Boxing Champions (PBC) reporter Jordan Hardy, Harper said he didn't think he was getting paid enough for the bout.
His decision shocked those in attendance, some of whom started jeering as he made his way back up the ramp.
Here's the moment he left the ring.
In the other matches on Friday, hometown favorites Caleb Truax and Jamal James won their respective matches.
Truax stopped Fabiano Pena in the third round, while James took just two rounds to beat Mahonry Montes in the main event.
