The ONE Championship welterweight crown remained in the good hands of Kyrgyzstan native Kiamrian Abbasov Friday morning.

Abbasov (23-4-0) recorded a come-from-behind TKO victory over American James Nakashima (12-1-0) in the main event of ONE: Inside the Matrix. Nakashima started fast with punch that damaged the nose of Abbasov in the first round and piled up the points in the second and third rounds. But an Abbasov counter knee in the fourth round by Abbasov staggered Nakashima. Follow up strikes forced referee Justin Brown to call the bout at 3:27.

With the win, Abbasov collected his fifth straight victory, including his third straight in ONE and handed Nakashima his first defeat in 12 contests.
