Norma Dumont and Ailin Perez's weigh-in face-off turns heated, security intervenes

What was meant to be a routine pre-fight staredown ahead of UFC Fight Night escalated sharply on September 25 when Norma Dumont hurled condoms and money at Ailin Perez during their final face-off, forcing security to step between the two bantamweights before the situation could deteriorate further.

Dumont, who fights out of Brazil under the Team Rules banner, carries a 13-3 record into the bout and sits fourth in the women's bantamweight rankings at 35 years old. Standing five-foot-seven with a 67-inch reach, the orthodox striker known as "The Immortal" lands close to four significant strikes per minute and has shown a steady takedown game at 1.56 attempts per 15 minutes across her UFC career.

Her Argentine opponent is ranked one spot below her at fifth in the division. Perez, nicknamed "Fiona" and training out of The Goat Shed Academy, is 31 years old and holds a 13-2 record. At five-foot-five with a 66-inch reach, the switch-stance fighter posts an impressive 56 percent striking accuracy and is one of the division's more active wrestlers, averaging 4.9 takedown attempts per 15 minutes.

Why it matters

• Both fighters sit inside the top five at 135 pounds, making this a meaningful rankings bout with title implications further down the line.
• Dumont's higher striking volume against Perez's elite takedown threat sets up a sharp striker-versus-grappler dynamic.
• The bad blood on display at the face-off suggests neither fighter will be content to let the action play out at range come fight night.
