Alexandre Pantoja and Mauricio Ruffy have crucial duels for their careers at UFC 331 , scheduled for this Saturday (19). To have their arms raised, however, the Brazilians will need to overcome their underdog status in the betting houses in their respective fights on the main card, against Joshua Van and Arman Tsarukyan.

Considered one of the greatest champions in the history of the flyweight division (up to 56,7 kg), Alexandre Pantoja lost his belt in just 26 seconds after suffering an elbow injury against Joshua Van at UFC 323 in December 2025. Now, the Brazilian seeks to regain the title, but enters the octagon as an underdog, with odds of 2,20.

In practice, a R$100 bet on Pantoja to win would yield a total return of R$220. Someone betting the same amount on Joshua Van would receive R$171.

Alexandre Pantoja boasts a record of 30 wins, five of them in UFC title fights, and six losses. Joshua Van , on the other hand, has accumulated 17 wins and only two losses in his career.

Just like Alexandre Pantoja , Mauricio Ruffy enters the UFC 331 octagon as the underdog. The Brazilian faces Arman Tsarukyan in a duel that could determine the next challenger for the lightweight title (up to 70,3 kg).

To earn a potential title shot against Justin Gaethje , Ruffy will have to overcome not only the Armenian's strong wrestling skills, but also the odds from the bookmakers. With odds of 3,60, a R$100 bet on the Brazilian's victory would yield a total return of R$360.

Arman Tsarukyan , on the other hand, enters the octagon as the favorite. A R$100 bet on the 'Batman of MMA', with odds of 1,31, would yield a total return of R$131.

Another Brazilian in action on the main card is Patricio Pitbull . Like his compatriots, the former Bellator champion is considered the underdog in his fight against Dooho Choi.

A bet of R$ 100 on Patricio's victory would have a total return of R$ 315, while the same amount invested in the South Korean player, with odds of 1,36, would yield R$ 136.

The clear favorite on the card is Gable Stevenson , a protégé of Jon Jones , who is listed with odds of 1,04 to defeat Sean Sharaf.

A R$100 bet on the Olympic medalist would yield only R$4 in profit, totaling R$104 in return. On the other hand, a bet on the underdog Sean Sharaf, with odds of 13,00, would have a total return of R$1.300.
