Norma Dumont and Ailin Perez's weigh-in staredown escalates as security intervenes

Things got heated at the UFC Fight Night weigh-ins on September 25 when Norma Dumont escalated her face-off with Ailin Perez, throwing condoms and money at her Argentine rival before security was forced to step between the two bantamweights.

Dumont, known as "The Immortal," enters the bout ranked fourth in the women's bantamweight division with a 13-3 record. The 35-year-old Brazilian out of Team Rules stands five-foot-seven with a 67-inch reach and lands nearly four significant strikes per minute, making her one of the more active and aggressive strikers in the division.

Perez, the Argentine ranked fifth at 13-2, brings a contrasting but equally dangerous profile. The 31-year-old, nicknamed "Fiona" and training out of The Goat Shed Academy, is an elite grappler who averages 4.9 takedowns per 15 minutes — one of the highest rates in the women's game — and carries a striking accuracy of 56 percent, the higher of the two fighters heading into fight night.

Why it matters

• Both fighters sit in the top five of the women's bantamweight division, meaning the winner could push directly into title contention
• Dumont's striking volume advantage against Perez's takedown threat sets up a classic striker-versus-wrestler matchup
• The pre-fight tension raises the stakes heading into what was already a meaningful divisional bout
• A decisive performance from either fighter could reshuffle the rankings picture in a 135-pound division still taking shape
