According to the pro wrestling newsletter PW Torch, Hall is on life support after complications from hip replacement surgery earlier this month, the outlet said.
Representatives for the Georgia hospital where the outlet said he's being cared for.
In a post to Instagram on Sunday night, Hall's longtime friend and pro-wrestling teammate, Kevin Nash, said he will be taken off of life support once "his family is in place."
"Scott's on life support. Once his family is in place they will discontinue life support," wrote Nash, who formed the famed World Championship Wrestling (WCW) tag team "The Outsiders" with Hall in the 1990s.
"I've been blessed to have a friend that took me at face value and I him," Nash said of Hall, who also went by the moniker "Razor Ramon" in his early career. "When we jumped to WCW we didn't care who liked or hated us. We had each other. ... We were the 'Outsiders' but we had each other." "Scott always felt he wasn't worthy of the afterlife. Well God please have some gold-plated toothpicks for my brother. My life was enriched with his take on life. He wasn't perfect but as he always said 'The last perfect person to walk the planet they nailed to a cross.' As we prepare for life without him just remember there goes a great guy you ain't going to see another one like him again. See Ya down the road Scott. I couldn't love a human being any more than I do you."
