Nate Diaz returns to the octagon one last time for what looks an incredibly daunting five-round bout clash with Khamzat Chimaev.
The 37-year-old is competing in his final contracted fight in the promotion and has been paired with a contender in soaring form.
Without a win in over three years, meeting Chimaev is some way to go out.
Elsewhere on the card, a struggling Tony Ferguson attempts to reignite his career at a new weight class while Kevin Holland looks to continue his comeback.
