You have to be a certain kind of person to get into the world of professional fighting. Even saying that, you REALLY have to be a certain kind of person to get into the Bare Knuckle Fighting Championship.

The BKFC is exactly what it sounds like. Man-to-man, woman-to-woman combat, without those pesky padded gloves involved. The bloody sport brings some pretty incredible moments in the world of combat sports, but there may not be any moment quite as explosive as this three-second knockout.

Absolutely bonkers.

It took Ulysses Diaz just three seconds to finish Donelei Benedetto, officially marking the fastest finish ever in the organization. That’s the sort of performance that can make a fighter, and Diaz likely could have stepped in and fought another opponent immediately afterwards if there were an opportunity.
