Brendan Allen’s next fight
Allen’s next fight is at UFC 318, where “All In” takes on Marvin Vettori on the preliminary card.
Their rivalry began not in the octagon, but after a PFL event in the casino. Vettori had a disagreement with Tuco Tokkos before Allen stepped in to attack Vettori, sending him back into a roulette table.
This occurred in August 2024. It has taken nearly a year to get these two fighters to step into the octagon to face each other in what should be a heated contest.
Brendan Allen vs Chris Curtis
Allen has had two fights with Curtis in the UFC so far, with each man winning one fight apiece in the octagon.
The first bout was held at a UFC Vegas event in December 2021, where Curtis caught out Allen to win via a crushing TKO, thanks to a flurry of punches and knees without reply.
The rematch at UFC Fight Night: Allen vs Curtis 2 was much closer, going all five rounds to the delight of the UFC faithful.
In that encounter, Allen walked out victorious after the judges awarded him a split-decision win.
