Kayla Harrison Shares Post-Surgery Update Following UFC 324 Withdrawal

UFC bantamweight champion Kayla Harrison underwent neck surgery, forcing the postponement of her UFC 324 title defense, announced Wednesday. The procedure addressed herniated disc issues and delays her co-main event with Amanda Nunes, with the promotion planning to rebook. News of Kayla Harrison neck surgery followed her social media update from New York, where Dr. Han Jo Kim performed the operation. Harrison, 35, has not missed a bout since turning pro in 2018 and previously went 14-0 in the PFL before a 2022 loss to Larissa Pacheco. She debuted in the UFC with a win over Holly Holm, then beat Ketlen Vieira and Julianna Pena to claim the title. Medical guidance estimates recovery at 12 weeks or more; no interim belt is planned.
