The main event, billed as a crucial test for Pimblett against one of the division’s most battle tested fighters, ended with the Liverpool native emerging victorious after a grueling contest that showcased discipline, durability, and composure under pressure.

How the fight unfolded

Gaethje entered the bout as the experienced power striker, pressing forward early and looking to dictate the pace with leg kicks and heavy exchanges. Pimblett weathered the opening pressure, choosing movement and timing over reckless engagement.

Gaethje absorbs rare setback

For Gaethje, the loss is a notable setback in his pursuit of another title run. Known for resilience and high output wars, he struggled to impose his usual tempo as Pimblett disrupted exchanges and avoided prolonged firefights.
