Both Figueiredo and Moreno were turning around just three weeks after fighting, and after the champ made weight, his rehydration did not go well. He ended up in the hospital and at one point, he thought the fight was off.
"It was 30 hours of nightmare," said Figueiredo's manager, Wallid Ismail to ESPN. "When he ate the soup, everything fell apart. He threw up a little bit and it started the nightmare. We get out from there, we go direct to the hospital."
According to his manager, Deiveson Figueiredo was in the hospital from 2:30 am to 6:30 on the morning of the fight. It even got serious enough that Ismail called the UFC to tell them the fight was likely off.
"His belly's that size," Ismail said. "Everybody was like, 'He's not going to fight.' I called the UFC and said, 'Hey man, the guy is really bad right now.' We get to the hospital at 2:30 a.m. [local time], unbelievable. He said he could feel a lot of pain. I said, 'The fight is gone.'"
Despite being hospitalized, Figueiredo told his manager he planned to fight and that he was ready to go to war.
"He looked to me, 'Yes, I'm going to do it,'" Ismail said. "Now he's going to fight. The mindset of everybody is war, we're going to war."
What's next for Deiveson Figueiredo after UFC 256?
With Deiveson Figueiredo able to fight, he told his team he needed to finish Brandon Moreno quickly or the fight would not go well for him.
"My feeling in the locker room, was like an animal, furious, like a tiger," Figueiredo said. "My mindset was to knock out the guy. ... But unfortunately, [I] cannot do it."
Now, following the fight, which was declared a draw due to a point being deducted, Figueiredo is anticipating a rematch. He says he hopes the fight can happen in June as he wants a couple months off after fighting twice in under a month. When he rematches Moreno, Figueiredo is confident he will finish him at full health.
"If I'm not sick, I knock out him or submit him in the first round, that's a promise," Figueiredo concluded. "I'm much more stronger, I'm much more faster."
For now, Figueiredo is healing up after his fight and will get back to training in 2021.
