Bear in mind, that Rousey was coming off her first MMA loss—a brutal KO stoppage at the hands of Holly Holm in 2015.
Regardless, Rousey had taken a long hiatus from MMA competition and worked tremendously hard on her strength and conditioning ahead of her UFC 207 fight with Nunes.
Nunes finished off Rousey in 48 seconds of the very first round—measuring Rousey with a few power jabs, and then tagging her with 1-2s.
In what was one of the most brutal standing TKO stoppages in MMA history, Nunes’ 1-2 and powerful straight punches had Rousey out on her feet—further cementing The Lioness’ legacy as one of the best fighters in WMMA history.
