Dan Hooker withdrew from his highly anticipated UFC 313 co-main event fight against Justin Gaethje due to a hand fracture sustained during training. This cancellation marks a significant loss for the event, which was eagerly awaited as a 'fight of the year' matchup. Hooker confirmed the injury on his daughter's YouTube channel, showing his swollen hand and revealing the fracture was discovered via CT scan. Potential replacements include Rafael Fiziev, Renato Moicano, and Mateusz Gamrot, who have expressed interest. Gaethje, last seen in a knockout loss, awaits a new opponent, while Hooker, on a three-fight win streak, hopes to reschedule. The main event remains as Alex Pereira defends his title against Magomed Ankalaev.
