16-1 Brazilian Rogerio Bontorin, 27, fought at bantamweight throughout his career, but when an opportunity arose to get on Dana White's Contender Series, and it was at flyweight, he took it. Bontorin won, was awarded a UFC contract, and is now 2-0 in the league headed into a fight vs. Ray Borg at UFC on ESPN+ 25 on Saturday night.
He hasn't missed weight, but trains twice a day during fight week, on Wednesday had 12.8 pounds to go, and it gets worse.
"I can't eat during fight week," he said to Guilherme Cruz for MMA Fighting. "I don't eat anything. ... I'm in this weight class because that's the spot that was open. For now, while I still can make weight, I'll stay here. It depends on my body. I'm still getting used to the weight class, actually. I only fought three times in this division, but it's working for now. ... I still can do it. When I can't no more, then I'll think about going back."
Ranked #7 in the UFC at flyweight, Bontorin has the highest-profile fight of his career on Saturday.
"It's an important fight because of his name, but all fights are tough," said Bontorin. "I won't let that add an extra weight in my head. He has a name, but I have more fights and more wins than him. ... What he does is take people down, right? He's a wrestler. That's all I think he does. Let's see what happens in the fight. I've prepared myself for this because he trades a little bit on the feet in the beginning of the fight and then goes for a takedown, so let's trade and see what happens."
On Saturday Bontorin will engage in as demanding a sport as has ever been devised. And the week before it, he doesn't eat.
