Jai Herbert ’s first lightweight title defense came in the Cage Warriors 109 main event when he scored perhaps the most devastating result of his career thus far against Cain Carrizosa . Herbert (10-1) was a man on a mission in the headlining bout against Carrizosa (11-4), which took place at Resorts World Arena in Birmingham, England, and streamed on UFC Fight Pass. The champion became the first to stop his challenger with strikes, landing a perfectly placed knee for the knockout in less than four minutes
