Fenomeno

Brazil
New opponent scheduled
Vieira is scheduled to compete against Norma Dumont in a bantamweight fight at UFC Vegas 110 on Nov. 1, per Marcel Dorff of Eurosport.nl.
ANALYSIS
For half a year, Vieira had been dealing with a debacle in terms of trying to fight Macy Chaisson. However, that is no longer an issue, especially after Vieira outlasted Chaisson in May. Up next for Vieira is Dumont, previously scheduled to fight a former UFC champion in Raquel Pennington.

Gets right back in win column
Vieira defeated Macy Chiasson via unanimous decision (29-28, 29-28, 30-27) at UFC Fight Night on Saturday in Las Vegas.
ANALYSIS
Vieira had weight cutting issues entering this fight, forcing it to be moved from bantamweight to featherweight. It ended up being a huge break for her in the end. Ketlen failed on her lone takedown attempts, but still managed to rack up 10:06 worth of control time. She didn't land many notable offensive blows, but when you combine the control time with a 106-52 edge in total strikes landed, you're going to win a decision. Vieira has alternated wins and losses in her past five fights dating back to May 2022.
