We have you covered for all of tonight's UFC 331 results, including the heavyweight matchup between Robelis Despaigne and Tai Tuivasa.

Despaigne (6-2 MMA) will be returning to the Octagon for the first time since scoring a first-round knockout victory over former UFC champion Junior dos Santos this past May at MVP MMA's ‘Rousey vs. Carano' event (see that here). Prior to that triumph, ‘The Bad Boy' was coming off back-to-back decision losses to Austen Lane and Waldo Cortes-Acosta.

Meanwhile, Tai Tuivasa (14-10 MMA) will enter tonight's contest with hopes of snapping a seven-fight losing skid. ‘Bam Bam' most previously competed this past May at UFC Perth, where he suffered a unanimous decision loss to Louie Sutherland. The 33-year-old earned his last UFC win way back in February of 2022, when he knocked out Derrick Lewis.
