UFC 324 is the first numbered UFC event of the new year, headlined by a lightweight bout between Justin Gaethje and Paddy Pimblett, and also featuring stars like Sean O'Malley.

It wasn't to be for Paddy Pimblett in his quest to become UFC lightweight interim champion as Justin Gaethje rolled back the years.

Gaethje, 37, will enter his fourth UFC title bout having won three of his past four fights, coming off a unanimous decision win over Rafael Fiziev last March.
