Ailin Perez draws a line: she won’t fight if Macy Chiasson misses weight in Mexico City
ailin perez has demanded a firm condition ahead of her bantamweight meeting with Macy Chiasson: if Chiasson misses weight, Perez says she will not step into the Octagon at UFC Mexico City on Saturday, Feb. 28, 2026, inside Arena CDMX in Mexico.
Ailin Perez issues ultimatum over weight
Perez, the No. 7-ranked UFC women’s bantamweight, told interviewers she does not see Macy Chiasson beating her in “any way or any area” and that she will refuse the fight if Chiasson fails to make the bantamweight limit for the Feb. 28 card at Arena CDMX.
Perez’s concerns and past weigh-in history
Perez said she has watched Chiasson at the UFC Performance Institute and thinks Chiasson “looks like she might not make weight. ” Perez pointed to Chiasson’s recent history: Chiasson did not make weight for her last fight and the one before that, and earlier offered a catchweight against Ketlen Vieira because she was not going to make the weight.
Chiasson’s record and recent form
Macy Chiasson (10-5) comes into the Mexico City bout off back-to-back defeats — decisions to Yana Santos and Ketlen Vieira — marking the first consecutive losses of her UFC career, a stretch that a preview called a moment where she could be fighting for her UFC life.
How Perez has been winning and the matchup dynamics
Ailin Pérez (12-2) arrives on a five-fight UFC winning streak, with wins that included grinding out Karol Rosa, overwhelming Darya Zheleznyakova and fending off Joselyne Edwards with clinch pressure and top control. Perez’s path typically involves chaining takedowns from the clinch, heavy top control and constant wrestling pressure that wears opponents down.
Size, styles and strategic edges
Chiasson is a large bantamweight — listed as having a 5-foot-11 frame in the matchup preview — who relies on a long jab, teeps and the ability to muscled clinch work, front chokes and back takes when she controls position. Recent notes name Chiasson’s finishes of Mayra Bueno Silva and a submission of Pannie Kianzad as examples of improved finishing ability when she secures dominant positions.
The same preview argued Perez’s clearest route is to turn the fight into a grinding affair that neutralizes Chiasson’s length: body-locks, inside trips and mat returns that sap Chiasson’s gas tank, a phase where Perez has continued to succeed, especially in Mexico City’s altitude.
Prelim context, odds and a truncated pick
The Chiasson–Perez bout is set for the prelims of the UFC Mexico City card that also features Brandon Moreno vs. Lone’er Kavanagh on the same show. The preview referenced UFC Mexico City odds courtesy of DraftKings and a viewing note mentioning fuboTV’s live sports option.
The analytical preview ended mid-sentence, leaving its final pick unclear in the provided context.
Weigh-ins, officials and what’s next
Perez said she has spent the last three months preparing both to make weight and to fight and that she will not accept excuses. Perez also admitted she would have preferred other opponents ranked above her, such as Norma Dumont, called this matchup “very boring and ugly” but added, “A finish is coming, just like you guys saw in France. ” With Perez standing firm, UFC officials will need to keep a close eye on the official weigh-ins ahead of the Feb. 28, 2026, card at Arena CDMX to determine whether the Chiasson fight will proceed.
