• Gane edges Hokit on points to retain heavyweight crown

Kayla Harrison retained her UFC women's bantamweight championship with a fourth-round submission of Amanda Nunes on Saturday night at Madison Square Garden, spoiling the comeback bid of the woman widely regarded as the greatest female fighter in MMA history.

Harrison (20-1) had plenty to prove in her first title defense against Nunes, who ended a three-year retirement for the long-awaited showdown. It was also Harrison's first fight since June 2025, after spinal fusion surgery in January to address a neck injury forced the postponement of the bout.
