Khabib Nurmagomedov will fight for the first time since his clash with Conor McGregor when he faces Dustin Poirier at UFC 242 in Abu Dhabi in September.
UFC lightweight champion Nurmagomedov beat McGregor at UFC 229 in October to extend his unbeaten record to 27-0.
The 30-year-old Russian was then fined and banned for nine months for a brawl following his win over the Irishman.
Poirier, 30, holds the interim title after beating fellow American Max Holloway in April.
The championship fight will take place on Saturday, 7 September.
