De Ridder’s UFC 311 Weight Jump Revealed a Much Bigger
Reinier de Ridder weighed 212 pounds on fight night at UFC 311 on January 18, 2025, after officially weighing in at 184.5 pounds. California commission figures reported by MMA Fighting showed a 27.5-pound increase between the two measurements.
The middleweight matchup had a substantial size difference
De Ridder faced Kevin Holland in the opening main-card bout at Intuit Dome in Inglewood, California. Holland’s recorded weights rose from 183.5 pounds at the official weigh-in to 190.4 on fight night.
That left de Ridder 21.6 pounds heavier when the fighters competed. He won by rear-naked choke at 3:31 of the first round, earning another submission victory in his early UFC run.
Both bantamweight finalists reached the same weight
The championship co-main event provided another striking comparison. Merab Dvalishvili officially weighed 134 pounds before reaching 156.8, an increase of 22.8 pounds.
Umar Nurmagomedov also reached 156.8 pounds after weighing in at 135. Although their starting measurements differed, the commission’s fight-night figures put the bantamweight opponents at the same weight.
The main event showed another large increase
Renato Moicano went from 155 pounds to 181.8, while lightweight champion Islam Makhachev went from 154.5 to 178. The larger fight-night measurement therefore belonged to the challenger.
These figures document changes between official weigh-ins and competition rather than an overnight increase in muscle. Across the card, fifteen fighters exceeded a ten-percent gain, illustrating how different official scale weights can be from the measurements recorded when athletes actually fight.
