Kayla Harrison Nearly Retired Before Nunes Title Fight at UFC 334
Five herniated discs and neck surgery almost ended Harrison's career. At 36, she admits the Amanda Nunes bout could be her last.

Kayla Harrison will walk to the cage next month as the UFC women's bantamweight champion, but there was a stretch this year when she wasn't sure she'd walk to one ever again. The two-time Olympic judo gold medalist defends her belt against Amanda Nunes in the co-main event of UFC 334, a fight originally booked earlier in the year before neck surgery forced a postponement. Nunes, who returns at 23-5 (13 KO, 4 SUB), is one of the most decorated fighters in the sport's history.
Harrison told Uncrowned she had lived with five herniated discs for most of her career, managing them with stem cells, anti-inflammatories, nerve medication and relentless physical therapy to avoid going under the knife. That maintenance plan collapsed last December, when she lost feeling in three fingers, started getting what she described as lightning bolts down her arm, and lost strength in her right side. An MRI confirmed the two worst discs were completely pinching the nerve.
From Baddest on the Planet to a Neck Brace
The surgery that followed demanded a long, humbling recovery. Harrison said she went from training at 100 miles an hour for the biggest fight of her life to eight weeks in a neck brace, barred from lifting more than 20 pounds. She admitted there were real moments where she questioned whether she could do this anymore. The nerve pain vanished immediately after the operation, but the bone healing and muscle rehab dragged on, and she said the mental side of the drop-off hit just as hard.
Now fully healthy, Harrison says she's in a good place — a sharp contrast to a long stretch where she wasn't, and where she genuinely wondered if she had to make peace with being finished. She credited the slow climb back to confidence and shape with trusting the process and her faith.
Is This the Last One?
At 36, Harrison has little left to prove in MMA, and she's open about the possibility that Nunes could be her final fight. She said she's already satisfied with her career and could walk away tomorrow with peace. The caveat was pure Harrison: anything's possible, and she floated the idea of a $10 million payday keeping her around. For now, she's framing this one as a personal challenge against a worthy opponent who brings out her best.
The matchup itself carries weight regardless of what comes after. Nunes, a former two-division champion, hasn't fought since a unanimous decision over Irene Aldana. Harrison wants her specifically, and the bantamweight picture tilts on the result either way. May the best woman win — and if Harrison has her way, win or lose, she gets to decide the ending on her own terms.
