Chuck Wepner Charles "Chuck" Wepner (born February 26, 1939) is an American former professional boxer who fought at heavyweight. As a world ranked contender he fell just seconds short of a full fifteen rounds with world heavyweight champion Muhammad Ali in a 1975 title fight. Wepner also scored notable wins over Randy Neumann and Ernie Terrell.
Gorilla Jones William Landon Jones (1906–1982) known as "Gorilla" Jones, was an American boxer who held the NBA Middleweight Boxing Championship of the World. Although he was nicknamed "Gorilla" for his exceptional reach, Jones is to be distinguished from the original "Gorilla Jones", who campaigned from 1913 to 1924 and held the World Colored Welterweight title. Jones was never knocked out although he himself won by 52 knockouts out of 101 wins over 141 total fights. He was posthumously inducted into World Boxing Hall of Fame in 1994 and the International Boxing Hall of Fame in 2009.
