Watch: Nam scores buzzer-beater KO against top flyweight Bagautinov

Tyson Nam is at it again.

The gifted, yet inconsistent fighter pulled off the second major upset of his career on Friday, knocking out one-time UFC flyweight title challenger Ali Bagautinov with a shocking head kick. The strike ended the fight with just one second remaining in the final round of their main event bout in Moscow.

It was a shocking result given that Bagautinov is a top-10 talent at 125 pounds who was was fighting in his home country.

Then again, this isn't the first time Nam has done this.

Back in 2012, Nam traveled to Rio de Janeiro to fight Brazilian star Eduardo Dantas. At the time, Dantas held the Bellator bantamweight championship, but he was knocked out cold by Nam just 96 seconds into the non-title affair:

Any elite fighters out there may want to think twice before risking their reputations against Nam in the future.
