Roberts, 58, revealed he has a cancerous tumor behind his knee and that he will undergo emergency surgery to remove it.
Since Roberts caught the cancer in its very early stages, there's a great chance he'll survive and recover from the surgery quickly.
Roberts says he still plans to attend the upcoming WWE Hall of Fame Induction Ceremony in New Orleans, as he joins The Ultimate Warrior in the class of inductees for 2014.
"If the devil can't defeat me, cancer doesn't stand a chance in hell! Pray for sick children who face this horrible disease 'cause The Snake will be just fine," Roberts said.
Roberts is perhaps best known for his stints in the WWF - the first between 1986 and 92, and the second between 1996 and '97.
Throughout his pro wrestling career, Roberts was a fan favorite for his intense promo videos, his dark, charming presence and his signature DDT maneuver.
Roberts brought a snake to the ring whenever he had a bout, and WWE fans absolutely loved it.
"The Snake" recently returned to the WWE towards the end of a recent episode of "Old School Raw," as he put his snake, Damien, on The Shield's Dean Ambrose. Roberts' appearance on "Raw" seemed to signal a new era for him.
WWE fans believed his cameo would lead to many more appearances by Roberts.
Roberts was rumored to appear at the WWE 2014 Royal Rumble, but that one would never come to fruition.
Time will tell how his new ordeal with play out. Thoughts and prayers go out to the Roberts family at this time.
