The former Ultimate Fighting Championship middleweight titleholder and the former welterweight title challenger will meet at RAF 13 on Sept. 18 at Watsco Center in Coral Gables, Florida. The pair previously faced off at UFC 273, where Chimaev edged Burns via decision.
Khamzat Chimaev and Gilbert Burns will meet at RAF 13 four years after their UFC 273 classic
The RAF matchup comes over four years after Chimaev and Burns squared off in one of UFC's most memorable bouts of 2022, which earned Fight of the Night honors.
Chimaev already has another RAF assignment locked in before the Burns match. “Borz” is scheduled to face former UFC champion Tyron Woodley in the main event of RAF Moscow on Sept. 5. He made his RAF debut earlier this year against Dillon Danis.
Meanwhile, Burns announced his retirement from mixed martial arts following a loss to Mike Malott in April. The defeat was his fifth straight. Since stepping away from MMA, Burns has turned his attention to management and has also competed in UFC BJJ. The upcoming match with Chimaev marks the Brazilian’s debut in RAF.
