Why is Rosas Jr. - Barcelos a historic main event?

Because no fighter this young had ever headlined one. Rosas Jr. already holds the promotion's precocity records: signed at 17, he became its youngest winner on his debut in December 2022. He turns 22 on October 8.

He comes in at 6-1 in the UFC on a five-fight winning streak, with the reputation of a wrestler who keeps his opponents on the mat. Barcelos, 39, is seventeen years his senior, also on five straight wins, and brings a grappling pedigree inherited from his father, a wrestler on the Brazilian national team.

Who will win The Ultimate Fighter 34?

Both finals of the season, contested between Daniel Cormier's and Michael Bisping's teams, are on the main card.

At bantamweight, Mehemmedeli Osmanli (12-1) and Ilimbek Akylbek uulu (10-3), both from Team Bisping. At women's strawweight, two Team Cormier fighters: Melissa Amaya, unbeaten in eight fights, against Tina Black (15-4), a former Invicta FC champion.

What else is worth watching?
