The big boys are back to close out the show for 2021 as former interim and undisputed world title challenger Derrick Lewis takes on fellow knockout king Chris Daukaus at the UFC APEX.

Lewis will be keen to take some winning momentum in 2021 after coming up short against Ciryl Gane for the interim belt at UFC 265 last time out, while Daukaus enters the bout looking for a fifth straight KO since joining the promotion.

There's also an intriguing welterweight contest to look forward to as Stephen 'Wonderboy' Thompson takes on Belal Muhammad with both men eyeing an assault on the top five in 2022.

And with a handful of other cracking fights on the final card of the year, you won't want to miss out on UFC Fight Night: Lewis vs Daukaus.
