Jiri Prochazka made the first defence of his RIZIN Light Heavyweight Championship on Tuesday, stopping C.B. Dollaway via a first-round knockout at RIZIN 20, at Saitama Super Arena in Saitama, Japan.

The fight was close for the first few minutes, but it ended abruptly after Prochazka landed a left hook which dropped Dollaway, bouncing him on the canvas. No extra strikes were needed to give Prochazka the victory.

Prochazka has now won 10 in a row with a streak which started in 2016. He became the promotion’s first light heavyweight champion in April defeating King Mo, avenging a loss from 2015 with punches in the third round.

This fight was the first one outside the UFC for Dollaway since 2007. He left the UFC after being given a two-year suspension for a USADA violation.
