The heavyweight UFC 3 fighter, who earned a place in the Guinness Book of World Records as the world's largest living athlete, passed away on Monday (21Dec15) in Richmond, Virginia.

A cause of death for Yarborough, who stood at six feet, eight inches (two metres) tall and weighed 800 pounds (363 kilograms), has yet to be revealed.

He began his career in UFC 3 in 1994, but lost his first sumo fight against the much smaller Keith Hackney, who delivered a total knock out and earned the nickname "The Giant Killer".

Yarborough had previously also dabbled in American football and judo.

He went on to appear in 1997 movie Mr. and Mrs. Khiladi, alongside Bollywood star Akshay Kumar, while he also scored a role as inmate Clarence Seroy in crime drama Oz, and played himself in German wrestling film Sumo Bruno in 2000.
