Jim “The Anvil” Neidhart, who joined with brother-in-law Bret Hart to form one of the top tag teams in the 1980s with the WWE, has died. He was 63.

The Pasco Sheriff’s Office said Neidhart fell at home, hit his head and “succumbed to his injury” on Monday in Wesley Chapel, Florida. No foul play was suspected.

Neidhart’s daughter, known as Natalya, wrestles for the WWE and is a former women’s champion. Neidhart made appearances with his daughter on the WWE reality series “Total Divas.”

“My dad was always a fighter,” she wrote in an Instagram post.

Neidhart, Bret “Hitman” Hart and manager Jimmy “The Mouth of the South” Hart made up the Hart Foundation stable in the 1980s and 1990s, and the tag team won two WWE championships.

“What a great run we had. I couldn’t believe how it took off,” Jimmy Hart told The Associated Press. “But the reason why was, Neidhart was such a great character back then. Bret was more cool, the girls loved him. Neidhart and myself were kind of the evil twins.”

Neidhart married Bret Hart’s sister, Ellie, and became part of the famed family wrestling dynasty in Canada.
