President of wrestling's world governing body FILA resigned from his position in the wake of the recommendation to drop the sport from the Olympics.
Switzerland's Raphael Martinetti had been the president of FILA since 2002, the BBC reports.
The sport must now vie with other fringe disciplines for a spot in future Games, following the International Olympic Committee's (IOC) decision.
Martinetti was issued with a vote of no confidence at a FILA executive committee meeting in Thailand, the paper said.
FILA member Rodica Yaksi of Turkey said Martinetti has given his resignation, adding the bureau has selected an interim president for the extraordinary congress that will be held in Budapest in September, during the world championships.
Yaksi added they voted and elected Nenad Lalovic from Serbia as the interim president for the congress, not the FILA president.
Fila vice president Tomiaki Fukuda said the governing body would continue to discuss wrestling's plight during the annual gathering in Phuket.
Modern pentathlon and taekwondo were thought to be the sports most at risk when the IOC met in Lausanne on Tuesday, but wrestling was the surprise choice.
It will now compete with seven other sports baseball/softball, squash, karate, sport climbing, wakeboarding, wushu and roller sports - for a place in the 2020 Olympic Games, the paper added. (ANI)
