Regian Eersel says he broke his arm in round two before knocking out George Jarvis

The ONE lightweight Muay Thai champion posted an X-ray of a fractured right forearm after recovering from a first-round knockdown to stop England's Jarvis in Bangkok.

Regian Eersel says he fought George Jarvis with a broken right arm from the second round until the fourth-round finish, and still knocked the Englishman out to keep his ONE lightweight Muay Thai world title.

"Broke my arm in the second round... Finished the fight in the 4th round," Eersel wrote on Instagram, over a hospital X-ray of his right forearm showing a fracture.

In the rematch at Lumpinee Stadium in Bangkok on Friday, Eersel cut Jarvis with a one-two and a flying knee, but Jarvis answered with a left hook that put the champion down in the first round. Eersel dropped Jarvis with a left hook of his own in the second, then went to work on his swelling right eye.

In the fourth, another left hook from Eersel sent Jarvis down again, and the referee stopped it at 1:39 because of the damage to the eye. It was Eersel's fourth straight defence of the title and took his record to 66-5.

Eersel had finished Jarvis in 84 seconds in their first fight at ONE Fight Night 34 in August 2025. This time the Englishman lasted into the fourth round and became the first of the two to score a knockdown.
