The UFC returns to Brazil on May 12 with one of the more intriguing cards of the year. Women's bantamweight champion Amanda Nunes will headline the night against No. 2 contender Raquel Pennington. Nunes, coming off a split decision win against Valentina Shevchenko last September, will look to defend her belt for the third time in a row. Pennington has battled back from injuries since her last fight, a unanimous decision victory against Miesha Tate in November 2016.

The co-main event is a battle of top middleweights in Ronaldo "Jacare" Souza facing Kelvin Gastelum. Both fighters saw their last matchups end in first-round knockout wins. Also on the card is top prospect Mackenzie Dern taking on Amanda Cooper, John Lineker vs. Brian Kelleher and a battle of Brazilian legends, Vitor Belfort vs. Lyoto Machida.
