Reinier de Ridder began Saturday's UFC Fight Night main event looking every bit the part of the higher-ranked middleweight, dominating the early grappling. But after Brendan Allen survived Round 1, he took over the fight and wore down de Ridder, to the point where at the end of both Rounds 3 and 4, de Ridder was barely able to climb off the mat and make it back to his corner. His coach stopped the fight before the fifth round could start.
It was a strong performance by Allen, who wasn't even supposed to be in this fight. Originally, de Ridder was scheduled to face Anthony Hernandez, but Hernandez withdrew because of injury. Allen was brought in on short notice.
Allen ended up serving notice to the rest of the middleweight division — and shifted the balance of power in the ESPN divisional rankings. He's now ahead of de Ridder.
The only other weight class with changes in these rankings is heavyweight, because Francis Ngannou has not fought in just over a year and was removed as ineligible. Expect changes in several weight classes next week, with nine ranked fighters scheduled for this coming weekend's UFC 321.
Here are the ESPN pound-for-pound MMA rankings and a list of current UFC champions in all weight classes.
Results are current; rankings as of Oct. 21. To be eligible for the rankings, a fighter must have competed over the past 12 months or must have an upcoming fight booked. Fighters who have been dropped for inactivity can be reinstated only after they compete.
Heavyweight | Light heavyweight | Middleweight | Welterweight
Lightweight | Featherweight | Men's bantamweight
Men's flyweight | Women's bantamweight | Women's flyweight | Strawweight
