Video: Ronda Rousey lasts just 48 seconds in UFC comeback fight

Ronda Rousey's UFC comeback after more than a year out of the octagon lasted just 48 seconds as she was brutally stopped by Amanda Nunes, who said afterwards: "I'm here to stay".

Rousey was seeking to regain the bantamweight championship she lost in November 2015 to Holly Holm, her first defeat in the UFC, but she proved no match for Nunes as her Brazilian opponent rained down punches from the opening bell.
