Jiri Prochazka made quick work of C.B. Dolloway at Rizin FF 20. It didn’t take long for the Rizin FF light heavyweight champ Prochazka (26-3, 11-1 Rizin) to retain his title, as he scored a first-round knockout over UFC veteran C.B. Dolloway at the Saitama Super Arena on New Year’s Eve. Prochazka marched down Dolloway (17-10, 0-1 Rizin), eating his leg kicks and pressing him towards the ropes. Shortly after, he threw a thunderous left hook, bouncing Dolloway’s body off the canvas.
