Jim Miller secured his 14th UFC submission victory at 42 years old, finishing his opponent with a guillotine choke at UFC 328. This fifth guillotine finish puts him just two fights away from the all-time UFC appearance record of 50 bouts. Miller already holds the record for most UFC wins with 28 and is second in total finishes with 20, trailing only Charles Oliveira's 21. In his last 10 fights after turning 38, Miller has gone 7-3 with all seven victories coming by finish. Miller's career was notably affected years ago when he contracted Lyme disease from a tick bite, which caused him to lose physical conditioning and change his body structure, though he successfully recovered.
Jim Miller cemented another milestone in his remarkable career at UFC 328 on May 9, submitting his opponent with a guillotine choke to record his 14th UFC submission victory at the age of 42.
Miller, who competes at lightweight and carries a professional record of 39-19-0, has long been one of the most durable and accomplished fighters in UFC history. The southpaw from Sussex County MMA stands five-foot-eight with a 71-inch reach and has built his reputation on a relentless submission game, averaging 1.7 submission attempts per 15 minutes across his career. The guillotine finish was his fifth of that specific variety, underlining just how sharp his finishing instincts remain deep into his 40s.
The American holds the outright record for most wins in UFC history with 28 and sits second in total finishes with 20, one behind Charles Oliveira's all-time mark of 21. Perhaps just as striking is what Miller has accomplished in the later stage of his career — since turning 38, he has gone 7-3 over his last 10 fights, with all seven victories coming by way of finish.
Miller's longevity is all the more impressive given the obstacles he has faced. Earlier in his career, a Lyme disease diagnosis following a tick bite caused significant physical deterioration, forcing him to rebuild his conditioning and adapt his body structure before successfully returning to form.
Why it matters
- Miller now stands just two fights from the all-time UFC appearance record of 50 bouts, a landmark that could fall within the next year
- His 14 UFC submissions are a record, and his finishing rate in the post-38 phase of his career reinforces his status as one of the sport's great veterans
- At 42, Miller continues to compete as a finisher rather than a survivor, which raises the stakes for whoever shares the cage with him next
