Brendan Allen captured the All-Stars grappling championship at ACB JJ 21 on July 5, 2026, after Ramazan Kuramagomedov's corner threw in the towel following a shoulder injury that left the undefeated Russian competing with one arm for a stretch of the match.
Allen, known as "All In," arrives at the middleweight crossroads of MMA and submission grappling as one of the more complete fighters in the 185-pound division. The 30-year-old American holds a 26-7 professional MMA record and is currently ranked fifth at middleweight while competing out of Kill Cliff FC. Standing six-foot-two with a 75-inch reach, Allen brings a well-rounded game to the mat, averaging 1.1 submission attempts per 15 minutes alongside a solid takedown rate of 1.56 per 15 minutes in MMA competition.
Kuramagomedov entered the contest with a perfect 8-0 professional record and, at 29 years old, has been one of the more electric offensive performers in recent memory. The Russian, who trains out of American Top Team, carries a striking accuracy of 67 percent in MMA and lands an eye-catching 11.67 significant strikes per minute — numbers that reflect an aggressive, forward-moving style. Despite the shoulder setback forcing the stoppage, Kuramagomedov showed considerable toughness by continuing to compete one-armed before his corner intervened.
Why it matters
- Allen adds a high-profile grappling title to his resume at a time when he sits just outside the middleweight top four in MMA
- The injury stoppage leaves questions about Kuramagomedov's shoulder health heading into future competition
- The matchup pitted Allen's submission-oriented ground game against one of the division's most prolific strikers, making the grappling format a meaningful stylistic test
