Former UFC heavyweight champion Frank Mir made his professional boxing debut against Steve Cunningham at tonight’s Triller: ‘Askren vs. Paul’ event.

Mir (19-3 MMA) was originally slated to meet Antonio Tarver at tonight’s event, however the Georgia commission would not allow the former boxing champion to compete.

With that, Frank Mir was quickly rebooked, this time to fight former IBF cruiserweight champion Steve Cunningham.

Cunningham (30-9-1) had not competed since August of 2017, where he suffered a unanimous decision loss to Andrew Tabiti.

As for Mir, the former UFC heavyweight champion had most previously competed back in October of 2019, where he scored a unanimous decision win over Roy Nelson under the Bellator banner.

Tonight’s Frank Mir vs. Steve Cunningham fight proved to be a much more competitive contest than many were expecting. Through the opening four rounds of the fight Mir found some success while taking little punishment. However, Cunningham’s boxing skills began to show face later in the fight, as he proceeded to rock Frank Mir on multiple occasions. To his credit, the former UFC heavyweight champion hung in there and traded shots with the experienced boxer until the final bell.

Official Result: Steve Cunningham def. Frank Mir (60-54, 60-54, 58-56)
