RIZIN 24 live from the Saitama Super Arena in Japan. The promotion’s 28th event features a sold-out attendance of just 5,000 people due to government restrictions in place during the midst of the coronavirus (COVID-19) pandemic. In the night’s headliner, promotional superstar and Japanese combat-sports phenom Tenshin Nasukawa looks to remain undefeated when he takes on former K-1 title challenger Kouzi. The 22-year-old kickboxing prodigy seeks to add to an already impressive legacy in only his second bout of the year. Meanwhile, Kouzi is set to compete for the first time since leaving K-1 on a three-fight winning streak.
