2024 MMA retirement tracker: A list of those who hung up the gloves

Here’s a list of every notable retirement announced by fighters from the UFC, PFL, Bellator, and more in 2024.

(This story was updated to add new information.)

MMA is a constantly evolving sport with a revolving door of athletes entering and exiting. Currently, fighters from the era who helped make the sport so popular are beginning to trickle away from competition and hang up their gloves in order to move on to the next chapter in life.

If there’s one thing that’s well known about combat sports retirements, though, it’s that they often don’t last long. The urge to compete, and perhaps more importantly get a payday, will continue to drive fighters back even well beyond their expiration dates.

2024 has already seen a number of notable fighters announcing they are done with the sport, and we have a list of those who have opted to walk away this year (the list will update as new retirements are announced).

Rizin FF 27: Ayaka Hamasaki edges split-decision verdict to retain super atomweight title in Nagoya

Super atomweight champion Ayaka Hamasaki held on to her title by the slimmest of margins after earning a split-decision win at Rizin FF 27.

[autotag]Ayaka Hamasaki[/autotag] was pushed to the limit in her rematch against [autotag]Kanna Asakura[/autotag], but did just enough to earn the split-decision verdict from the ringside judges as she retained her Rizin FF super atomweight title by the slimmest of margins in Nagoya, Japan.

Hamasaki’s title bout with Asakura was the main event of Rizin FF 27, and saw the champion hang on to title after a grueling three round battle at Nippongaishi Hall.

After the fight was paused in the opening seconds for an accidental low blow, the action resumed with both women engaging in a wild exchange that eventually saw the action move to the canvas, with the champion on top.

Hamasaki (22-3) landed a pair of powerful knees to her downed opponent, but Asakura (18-5) showed her grit by battling to her feet, before picking up the champion and slamming her powerfully into the canvas.

Round 2 saw Asakura push the pace as she forced Hamasaki onto her back and set to work from the champion’s guard. But Hamasaki defended well and threatened with an armbar off her back before eventually escaping and returning to her feet. Asakura wouldn’t be denied, however, and after taking Hamasaki to the mat again, the challenger moved into mount and rained down a salvo of strikes as the bell sounded to save the champion from a TKO defeat.

After a cagey start to the final round, Asakura landed a takedown and pushed for a finish, but Hamasaki had successes of her own through the final stanza, as she attempted to snatch a final-round submission from the challenger with a standing armbar in the corner.

Neither athlete could make the crucial breakthrough, however, as the bout went to the judges, with Hamasaki hanging on to her title via split decision.
