Neidhart was a professional football player with the Oakland Raiders and Dallas Cowboys before he became a WWE wrestler. WWE Hall of Famer Stu Hart trained Neidhart in the Hart Dungeon in Calgary, Alberta, where Neidhart was nicknamed "The Anvil" after he won an anvil throwing contest. He went on to marry Hart's daughter, Ellie, and became part of wrestling's legendary Hart Family.

Together with Bret Hart, Neidhart won two WWE World Tag Team Championships. The two Canadians, along with other Hart Foundation members, were known for ragging on Americans during their performances.
