UFC 334: Macy Chiasson Faces Must-Win Moment Against Bia Mesquita
For Macy Chiasson, UFC 334 represents more than just another opportunity to step inside the Octagon. When she faces Bia Mesquita on November 14 at Madison Square Garden, the stakes could be particularly significant for the former Ultimate Fighter winner as she looks to reassert herself in the UFC women’s bantamweight division.
At 35 years old, Chiasson remains a ranked contender, currently sitting at No. 9 in the women’s bantamweight rankings. However, with a dangerous opponent standing across from her and questions surrounding her recent results, there is little room for another setback.
This is beginning to look like a must-win situation for the Louisiana native.
A career that needs a turning point
Chiasson has experienced plenty of highs during her UFC career. Winning The Ultimate Fighter 28 tournament established her as a fighter capable of competing at the highest level, while victories over respected opponents such as Norma Dumont, Pannie Kianzad and Mayra Bueno Silva demonstrated her ability to challenge established names.

However, recent results have made her position in the division increasingly important to watch.
Losses to Ketlen Vieira, Yana Santos and Ailin Perez have raised questions about where Chiasson currently stands among the division’s contenders. Three consecutive defeats would be a difficult stretch for any ranked UFC fighter to overcome.
A victory over Mesquita would provide an opportunity to change that narrative and remind the division that Chiasson remains a serious threat.
Bia Mesquita presents a dangerous challenge
Standing opposite Chiasson will be Bia Mesquita, a highly accomplished Brazilian grappler whose submission credentials make her a particularly interesting matchup.
Mesquita is not simply another opponent looking to climb the rankings. Her grappling pedigree presents a genuine stylistic challenge, especially against someone who will need to demonstrate composure and intelligent decision-making throughout the fight.
For Chiasson, controlling the distance, making smart decisions in grappling exchanges and avoiding prolonged periods fighting on Mesquita’s terms will be crucial.
A win against an opponent with Mesquita’s reputation would also carry considerable value. It would give Chiasson something meaningful to build on rather than simply adding another victory to her record.
