WWE legend Triple H led the tributes on Twitter, saying: "The only thing bigger than his on-screen character was his heart."

Jim won two World Tag Team Championships while competing in the 1980s and 90s with Bret "The Hitman" Hart.

Bret said he was "stunned and saddened" by the news.

Jim's daughter Natalya said she "can't put into words" how difficult it is to "say goodbye to my dad".

She also thanked fans for messages of support.

Former wrestler and actor Hulk Hogan called Jim "a real friend through the good and bad".

He trained with WWE Hall of Famer Stu Hart in Canada, teaming up with Stu's sons Bret and Owen Hart.

Jim married their sister Ellie and had three daughters, including wrestler Natalya.

He last competed in the WWE in 1997.
