This news makes his final speech made to a New Orleans crowd on last week's Monday Night Raw even more ominous...

Warrior said: "No WWE talent becomes a legend on their own. Every man's heart one day beats its final beat. His lungs breathe a final breath and if what that man did in his life makes the blood pulse through the body of others and makes them bleed deeper and something larger than life then his essence, his spirit, will be immortalised.

"In the back I see many potential legends. Some with warrior spirits and you will do the same for them. You will decide if they lived with the passion and the intensity. So much so that you will tell your stories and you will make them legends as well. You are the Ultimate Warrior fans and the spirit of Ultimate Warrior will run forever."
