According to the World Wrestling Entertainment website, Sullivan's heyday was in the 1970s and early 80s, when he won two tag team titles with his brothers.
He later managed wrestlers, including Hulk Hogan, and served as a commentator.
He was inducted into the hall of fame in 1996.
A man died after he was struck by a pickup truck Wednesday morning on McKnight Road in Ross Township, officials said.
Police said the man, who's in his 60s or 70s, ran across the busy road and was hit by the truck. He was not in a crosswalk.
"We do have witnesses. There was other traffic on McKnight at the time, so we were able to speak with people who actually witnessed the accident," said Ross Township Det. Brian Kohlepp.
The man, who has not been identified, died at a hospital.
"The driver of the truck stayed here on the scene. There's no indication that this was anything other than a terrible accident at this point, but we're still investigating," Kohlhepp said.
Southbound lanes of McKnight were closed in the area of Siebert Road while authorities investigated.
