It’s never a good idea to go to the mat with reigning RIZIN lightweight champion Roberto Satoshi Souza.
In the first of three world title tilts at RIZIN’s massive New Year’s Eve event inside the legendary Saitama Super Arena, Souza put his gold on the line against 20-win veteran Vugar Karamov.
It took Souza less than a round to score the 17th finish of his career, catching Karamov with a slick triangle choke and forcing him to tap out with only 15 seconds left in the round.
Official Result: Roberto Satoshi Souza def.
