Allen Frye Jr. Knocks Out RJ Harris at UFC Vegas 122

Allen Frye Jr. secured his first UFC victory by knocking out previously undefeated heavyweight RJ Harris in the opening round of UFC Fight Night 290. Frye Jr. needed just 2 minutes and 59 seconds to finish the fight, recovering from his previous promotional defeat while handing Harris the first loss of his professional mixed martial arts career.

According to the fight report published by MMA Junkie on October 10, 2026, the heavyweight matchup was the only bout in the division on the event card. Frye Jr. entered with a 7-1 professional record and a 1-1 UFC record, while Harris arrived at 6-0 professionally before the contest, with both fighters holding 1-1 records in the promotion after the result.

The fight developed into an exchange of heavy punches from the opening bell. Harris landed effectively early, but Frye Jr. absorbed the incoming shots and responded with strikes of his own, gradually putting his opponent under pressure.

As the exchanges continued, Frye Jr. landed clean punches that visibly affected Harris's balance. Recognizing that his opponent was hurt, Frye Jr. increased the pressure and pursued a stoppage.

The decisive sequence began with a counter left hook from Frye Jr., followed by a powerful right hand that sent Harris to the canvas. Frye Jr. continued striking on the ground until referee Herb Dean intervened to stop the contest at 2:59 of the first round.

The victory allowed Frye Jr. to rebound from the first defeat of his career, which came against Guilhereme Pat by unanimous decision in December. The win also marked his first UFC victory after losing his promotional debut.

Harris, meanwhile, suffered his first professional defeat after opening his career with six consecutive wins. He had made his debut with a first-round finish against Alvin Hines in July before facing Frye Jr. at UFC Fight Night 290.
