Chances are that if you score a walk off, knockout win you’re going to be a frontrunner for a “Performance of the Night” bonus, especially if it comes against a man who’s never been stopped in the Octagon.

Well, at UFC Fight Night 52 today in Saitama, Japan, Mark Hunt became the first fighter to stop Roy Nelson in the latter’s UFC tenure, and collected a “POTN” for his efforts.

If you missed it, Hunt wrapped up his main event bout with Nelson in round two, by sending the heavyweight crashing to the floor, face first, with a right uppercut. Mr. Hunt collected an extra $50,000 for the award.

With the win, Hunt is now 3-1-1 in his last 5 fights, with his only loss during that stretch coming to Junior dos Santos (yes, via the spinning hook kick).

Nelson, meanwhile, is 2-3 in his last 5 scraps now, as he’s also incurred decision losses to Stipe Miocic and Daniel Cormier (and has KO wins over Antonio Rodrigo Nogueira and Cheick Kongo).

The last time “Big Country” was stopped was way back in 2008, when he was taken out by Andrei Arlovski. That fight was with Elite XC…oh the memories.

The other “Performance of the Night” went to Johnny Case, for his second round, tap-out victory (via guillotine choke) over Kazuki Tokudome.

“Fight of the Night”, and $50 grand each, went to Kyun Ho Kang and Michinori Tanaka for their memorable war. Kang emerged from the battle with the split decision win.
