Former world heavyweight boxing contender Scott LeDoux has died at age 62 after battling Amyotrophic Lateral Scleroris (Lou Gehrig's disease).

His longtime friend and attorney Bob Dolan told The Associated Press Friday that LeDoux died Thursday at his Coon Rapids home after a nearly three-year battle with the disease.

The six-foot-one LeDoux was nicknamed the "Fighting Frenchman" and got the most out of his modest talent through heart and determination. He fought the top heavyweights of the 1970s, including Larry Holmes, George Foreman, Ron Lyle, Mike Weaver, Ken Norton, and Leon Spinks.

The Anoka, Minn., native challenged for the heavyweight title in July 1980, losing by seventh round stoppage to Holmes.

LeDoux sparred with Muhammad Ali, but a proposed bout between the pair fell through in that same year.

His professional ring record was 22-13-4 (seven knockouts), which included bouts in Edmonton, Winnipeg, and Vancouver.

Like many of the sport's big men, LeDoux only took up the sport in earnest in his 20s, after playing football most of his youth.

LeDoux was known as a straight shooter outside the ring, but in 1977 his anger led to one of the more humourous moments in televised boxing history.

After losing a controversial decision to Johnny Boudreaux in the ill-fated U.S. Boxing Championships tournament on ABC's Wide World of Sports, LeDoux instigated a melee that knocked the toupee off broadcaster Howard Cosell.

After retiring following a 1983 loss to Frank Bruno, LeDoux had a varied post-fighting career.

He worked as a boxing broadcaster, commissioner for Minnesota's boxing commission and wrestling referee.

LeDoux was survived by this third wife, Carol. Two previous wives preceded him in death.
