Ketlen Vieira

Fenomeno

Brazil

Gets right back in win column
BantamweightUFC
May 31, 2025
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.

Drops decision in Salt Lake City
BantamweightUFC
October 5, 2024
Vieira lost to Kayla Harrison via unanimous decision (27-30, 27-30, 28-29) at UFC 307 on Saturday in Salt Lake City.
ANALYSIS
Now 33 years of age and entering with victories in three of her last four bouts, Vieira found herself as a +675 underdog, by far the largest on the card. She managed to hang in there on the feet, but was predictably overwhelmed whenever the fight got to the mat. There's a case to be made that a Round 2 Vieira elbow was the most significant blow of the entire bout, but Ketlen had zero chance of winning a decision given her ground struggles in both the first and third frames. A member of the UFC roster for more than eight years now, it's entirely possible we have already seen the best the Brazilian has to offer inside the Octagon.
