Kayla Harrison retained her UFC women's bantamweight title on Saturday at Madison Square Garden in New York, submitting former champion Amanda Nunes with a rear-naked choke at 1 minute, 29 seconds of Round 4 at UFC 334. BBC Sport described it as one of the biggest women's fights in UFC history, while ESPN reported that Harrison had controlled the fight through takedowns after Nunes won the early striking. Nunes, 38, was returning from retirement after more than three years away and had won the bantamweight and featherweight titles, while Harrison, 36, is a two-time Olympic judo gold medallist and former PFL champion. Nunes said she came back to fight Harrison and to help grow women's MMA, and the two were former teammates at American Top Team. The bout had been postponed from January after Harrison had neck and spinal surgery. Afterward Harrison said she was a survivor of childhood sexual abuse and that she had many decisions ahead about her future.
