Allen Frye Jr. Stops RJ Harris in First-Round UFC Vegas 122 Bout

Allen Frye Jr. secured a first-round knockout against RJ Harris in the heavyweight division at UFC Vegas 122 on Saturday, October 10, 2026, at Meta APEX in Las Vegas, Nevada. Frye finished the fight with a series of right hands before the referee intervened, earning a victory that improved his professional mixed martial arts record to 7-1. The heavyweight matchup was the only fight in that division on the card, according to Cage Side Press.

Both fighters were making their second appearances in the UFC Octagon, with Harris entering the contest after winning his promotional debut and Frye seeking to overcome the only loss on his professional record. Harris, who had six professional fights before the bout, fell to 6-1. Frye, who had seven previous professional fights, advanced to 7-1 with the knockout victory, according to the source.

The fight opened with Frye attempting a spinning kick before both heavyweights exchanged powerful strikes. Harris connected with a jab roughly 30 seconds into the contest, appearing to stun Frye, and followed with outside leg kicks as he caught his opponent advancing.

Harris later landed a combination that included several punches, while Frye connected during the exchange. After the fighters reset in the center of the Octagon, Frye began landing multiple strikes that forced Harris to retreat. Frye then delivered four right hands to the side of Harris' jaw, sending him to the canvas. Frye followed up with additional strikes, prompting the referee to stop the contest moments later and award Frye the knockout victory.

Harris fought with his hands positioned low during much of the exchange, according to Cage Side Press. The report noted that this aspect of his performance could be a point of review following his first professional defeat. The victory continued Frye's record of finishing fights by knockout or technical knockout in the opening round. According to Cage Side Press, every one of his seven professional wins has come by first-round KO or TKO.
