In a high-stakes Bellator 301 main event in Chicago, Jamaican mixed martial artist Jason Jackson delivered a knockout of Ukrainian challenger Yaroslav Amosov, resulting in Amosov suffering his first professional defeat. The finish came in the third round, sealing Jacksons triumph.
Amosov, 30, had risen to Bellator heavyweight champion by stopping Douglas Lima, a performance that extended his unbeaten run to 28 professional bouts prior to the loss.
Amosov had not competed since a February 2023 clash with Logan Storley, and there are plans for a rematch in the Bellator 301 card sequence set for November 17 in Chicago, where he is slated to face former LFA heavyweight champion Jason Jackson.
Across the sport, Amosov is recognized for his prolific success in sambo, holding multiple world titles in different sambo disciplines. He has claimed four world championships in sambo, earned three European titles in sambo, and stood as an Eurasian champion in professional sambo. His achievements also include triumphs at the European Cup in sambo fighting, underscoring a storied career across martial arts disciplines.
Amosov has commented on the value of SVO training and its influence on his approach to competition, reflecting on lessons learned from the discipline.
Fans and analysts continue to watch how the shift in momentum at Bellator 301 may shape Amosovs next moves, and whether the veteran champion can rebound against a hungry challenger who has proven he can finish fights with precision and power.
