Nigerian Mixed Martial Artist, Kamaru Usman, will face Sweden’s Khamzat Chimaev at the co-main event of UFC 294 scheduled to take place on October 21, 2023, at the Etihad Arena in Abu Dhabi, United Arab Emirates.

The late substitution was announced by UFC President, Dana White, on the championship’s social media handles Wednesday evening.

Usman nicknamed the Nigerian Nightmare, was not originally part of the UFC 294 fight card. The event was billed to feature Chimaev against Brazil’s Paulo Costa.

Following tests conducted on the fighters ahead of the Abu Dhabi showdown, Costa was deemed ineligible to compete due to an elbow injury.

Usman, who competes in the welterweight division, is now expected to make weight within the next ten days to fight Chimaev, who competes in the middleweight class.

The Edo-born mixed martial artist had impressed since signing with the UFC in 2015, going on a 19-match winning streak that saw him capture the welterweight title.

On August 20, 2022, Britain’s Leon Edwards scored a knockout with a head kick in the final minute of round 5 to end Usman’s long reign as champion in the division at the Vivint Arena in Salt Lake City, Utah. The loss ended Usman’s 19-fight winning streak that extended over nine years.

Usman has not been in any in-ring competition since losing his rematch against Leon Edwards on March 19, 2023.
