Mason Jones to face MarQuel Mederos at Golden 1 Center on August 22

Welsh lightweight Mason Jones will face MarQuel Mederos at the Golden 1 Center in Sacramento on August 22. Jones, 31, enters on a seven-fight win streak that includes a fight-of-the-night bonus for his unanimous decision victory over Axel Sola in March.

Jones has earned performance bonuses in prior UFC bouts, including a stoppage win over Bolaji Oki in September 2025 and a fight-of-the-night award against Mike Davis on his debut in January 2021.

He holds a professional record of 18 wins, two losses and one no contest. Mederos arrives with a record of 11 wins, one loss and one draw after battling Chris Padilla to a majority draw in April. The Golden 1 Center serves as home to the NBA's Sacramento Kings.

Jones, from Blaenavon, previously trained with Team Alpha Male in the California capital. A victory for either fighter would improve their standing in the lightweight division. The card also features a middleweight bout between Anthony Hernandez and Gregory Rodrigues.

Justin Gaethje captured the undisputed lightweight title in June, while Paddy Pimblett remains the highest-ranked British fighter in the division.
