Most fighters spend their careers carefully managing risk. John Lineker has spent his tearing up that rule book entirely.
The Brazilian known as “Hands of Stone” has built one of the most compelling careers in ONE Championship not simply through his sledgehammer fists, but through an old-school mentality that is vanishingly rare in modern combat sports: when the call comes, he answers. No negotiations, no excuses, no hesitation.
That philosophy was on vivid display at ONE 165 in Tokyo, where Lineker was sitting in the crowd as a spectator when a last-minute withdrawal threatened to pull a bout from the card. Officials spotted him in the stands and offered him the fight on the spot. Within minutes, he was taped up and ready to compete against former ONE Lightweight MMA World Champion Shinya Aoki — a man who fights two full divisions above Lineker’s natural weight class.
That moment alone would define most careers. But Lineker was only getting started.

He later ventured into Muay Thai — a transition that elite MMA fighters almost never attempt — and made it look effortless. At ONE 168 in Denver, he stopped Asa Ten Pow in the second round on debut. A month later at ONE Fight Night 25, he dismantled the dangerous Alexey Balyko inside the opening round, silencing every remaining doubter in the process.
Then came kickboxing. Facing former ONE Bantamweight Kickboxing World Champion Hiroki Akimoto at ONE 172, Lineker turned the bout into a grinding war of attrition, losing a razor-thin split decision over three brutal rounds against one of the most technically gifted Japanese kickboxers of his generation.
Now the 35-year-old steps into yet another new challenge. He faces British striker Ben Woolliss in a featherweight kickboxing clash at ONE Fight Night 41: Sinsamut vs. Jarvis on Prime Video, live from Bangkok’s iconic Lumpinee Stadium this Friday, March 13.
For a man who once suited up from the bleachers, it is just another day at the office.
