Ronda Rousey fights Amanda Nunes for the bantamweight title at UFC 207 at T-Mobile Arena in Las Vegas on Friday night.
Rousey, 29, has not fought since losing her bantamweight crown to Holly Holm at UFC 193 in November 2015. It was the first loss of Rousey's career.
The title belt has changed hands twice since Rousey was dethroned. Holm lost to Miesha Tate with a fifth-round submissionu200b. Tate lost to Nunes in July in a fight that lasted just over three minutes.
This will be Nunes' first title defense since her victory at UFC 200 in July.
