Gerald Merschart is the lone fighter to miss weight ahead of UFC Perth, coming in 1.82 kg over the 84.37 kg middleweight limit at Thursday's official weigh-ins.
Merschart tipped the scales at 86.18 kg for his scheduled middleweight bout against Jacob Malkoun, who weighed in cleanly at 84.36 kg. As a result, Merschart will be penalized 30 percent of his purse, with that money transferred directly to Malkoun. Despite the infraction, the matchup remains on the card.
In the main event, welterweights Jack Della Maddalena and Carlos Prates both hit the mark at 77.11 kg, clearing the way for their headlining bout without issue. Heavyweights Shamil Gaziev and Tai Tuivasa, along with all other fighters across the card's 13 total bouts, also made weight without incident.
Why it matters
- Merschart's miss puts him at a physical disadvantage, as Malkoun had a proper weight cut and will rehydrate fully before the fight
- The 30 percent purse deduction is a significant financial penalty and a disciplinary measure designed to discourage repeat offenses
- The bout staying on the card is standard UFC practice when a miss falls within an acceptable range and both fighters agree to proceed
