ONE Championship Muay Thai fighter Fariya Aminipour has been killed in Phuket, according to his gym in Thailand.
The 23-year-old was said to have died in a "tragic accident" while on his bike, according to Tiger Muay Thai.
In a social media post, the gym paid tribute to "the extremely talented" fighter, who it said would be "missed greatly and will remain in all of our thoughts".
"At only 23 years old, lion-hearted Fariyar had already accomplished so much, and was well on track to achieving his dream of becoming a ONE world champion. Gone far, far too soon due to a tragic accident," the Instagram post said.
Aminipour was just starting to make his name in Muay Thai, he fought five times on the ONE Friday Fights series at Lumpinee Stadium last year, winning four of those bouts, all of which came at the expense of some high-profile opponents.
At ONE Friday Fights 4 he beat reigning Rebels super featherweight champion Hiroki Suzuki by decision, while at ONE Friday Fights 13 he scored a decision win over Ferrari Fairtex.
At ONE Friday Fights 22 he beat Rambolek Chor Ajalaboon who, like Ferrari, had been a champion at Thailand's Channel 7 Stadium, while his final victory of the year came at ONE Friday Fights 27 when Aminipour beat former Lumpinee Stadium champion Pongsiri PKSaenchaigym.
In his last fight of the year the Iranian took on another former fighter of the year, Kulabdam Sor Jor Piek Uthai, and was stopped in the second round at ONE Friday Fights 46.
