Two-time heavyweight champion George Foreman has died on the age of 76

American boxing legend George Foreman has died at the age of 76, his family have announced.

Foreman was an Olympic gold medallist in 1968 before claiming his first heavyweight title with a stoppage win over Joe Frazier in 1973.

He lost the belt a year later to Muhammad Ali in the Rumble In the Jungle bout. His second championship came more than two decades later at the age of 45, with a stunning knockout win over Michael Moorer in 1994 making him the oldest heavyweight champion ever.
