The cause of death was unknown, but the Pasco County, Fla., sheriff's department said foul play was not suspected, the Tampa Tribune said.
Bigelow worked for different professional wrestling organizations throughout his 20-year career. A former Extreme Championship Wrestling champ, an ECW Television champion and World Championship Wresting tag team champ, he was perhaps best known for his rivalry with Lawrence Taylor that wound up as the main event of 1995 WrestleMania XI.
In the mid-1980s, and at nearly 400 pounds, he performed drop kicks and other aerial maneuvers, perfecting a finishing move he called "Greetings From Asbury Park."
During his career, Bigelow shared a ring with Andre the Giant, Bret "The Hitman" Hart, Hulk Hogan and of others.
Of late, he partnered with "Roughhouse" Ralph Mosca, recently winning the American Championship Wrestling tag-team title.
Bigelow, who died Friday, is survived by three children.
