Quick Scoop

Ronda Rousey stepped away from fighting because of a long history of concussions and neurological injuries, which she said were a major reason she retired from MMA and later left WWE. Recent coverage also says she has been training again and, as of February 2026, publicly announced a return to MMA for a matchup with Gina Carano.

What changed

• She retired from UFC in 2016 after back-to-back knockout losses to Holly Holm and Amanda Nunes.

• In 2024, she said the real driver was health: concussions she had hidden for years, including injuries from judo before MMA.

• She later had a quieter exit from WWE and then stepped away from full-time combat sports.

• By late 2025, reports said she was back in the gym and training hard.

• In February 2026, she reportedly confirmed a comeback fight against Gina Carano, set for May 16 in Los Angeles.

Why people noticed

Rousey was once one of the biggest names in women’s combat sports, so any return or retirement news gets a lot of attention. Her story has also stayed in the spotlight because she shifted from a dominant run to a sudden retreat, then reappeared with a health-focused explanation.

Bottom line

What “happened” is mostly this: she didn’t just burn out or disappear — she said injury history forced her out, then she later re- entered the conversation with training updates and a reported 2026 comeback announcement.
