Spinks’ wife, Brenda Spinks, was by his side, in addition to a few close friends and family members when he passed away. He had been battling prostate cancer and other cancers for five years, Firm PR confirmed to CNN and ESPN.  

The boxer took on only eight fights into his professional career when he was 36 years old. Spinks’ victory is still considered one of the greatest upsets in history. 

“He had the will to win and the stamina,” Ali said about Spinks at the time, according to The New York Times. “He hit pretty hard.”

“It was one of the most unbelievable things when Ali agreed to fight him because you look at the fights he had up to then and he was not only not a top contender but shouldn’t have been a contender at all,” promoter Bob Arum said. “He was just an opponent but somehow he found a way to win that fight.”

Spinks began his boxing career in 1974 when he won three national AAU light heavyweight championships in a row and then went onto represent the United States in the 1976 Summer Olympics, where he took home the light heavyweight gold medal. He began his professional career in 1977 and beat competitors Bob Smith, Peter Freeman, Pedro Agosto and Alfio Righetti.

Spinks lost his WBC title when he refused to defend against Ken Norton in favor of a rematch with Ali months after their first fight, which Ali won. 

Spinks retired in 1995, but in 2017, he was honored by being inducted into the Nevada Boxing Hall of Fame. 

Spinks is survived by his wife and sons Cory and Darrell. His son Leon Calvin died in 1990 at 19 years old when he was fatally shot. Cory went on to become a welterweight and light middleweight champion in his own boxing career, and Leon’s brother Michael won the heavyweight title in 1985 and defended it three times before he was beaten by Mike Tyson in 1988.
