Amanda Nunes, posing before her UFC 213 fight in Las Vegas, is defending her bantamweight title for a third time Saturday.Amanda Nunes was told a year ago that she'd never return to a main event after falling ill before a scheduled UFC headline bout.But talent can't be denied."Exactly," Nunes said. "I'm the champion."With the UFC returning to Brazil, Nunes' homeland, on Saturday night for a pay-per-view card, the women's bantamweight champion defends her belt against Raquel Pennington."I knew everything would be fine," Nunes said of the previous admonishment from UFC President Dana White for bowing out of a fight against Valentina Shevchenko on the morning of a March 2017 card in Las Vegas."I was sick. I don't have anything to say sorry about. I want to fight at 100%. If I'm not 100%, I'm not supposed to fight. It's happened in all of the sports over the years. The times a football player has an injury, he doesn't play the next game, or if you're a little sick, you don't go. This is the case in all types of sports. Now I feel great."
