Findings from an autopsy on the body of pro wrestling great The Ultimate Warrior will not be immediately released, authorities said Thursday.

Warrior, 54, collapsed Tuesday while walking with his wife to a car outside a motel in Scottsdale, Ariz. He was pronounced dead at a local hospital.

Three days earlier, Warrior had been inducted into the WWE Hall of Fame at a ceremony in New Orleans. He had made an appearance on a Monday Night Raw telecast the evening before his death.

Authorities told The Associated Press that preliminary findings from the autopsy would not be disclosed until a later date, since determining the cause of death would take longer because it appeared to be medical-related.

Sources described the death as a "catastrophic medical condition," which could indicate a massive heart attack.

Scottsdale police said there were no signs of foul play.

Warrior, who was born James Brian Hellwig, legally changed his name to his wrestling moniker in 1993.

Warrior was one of pro wrestling's biggest stars in the late 1980s and early '90s. He defeated Hulk Hogan for the then WWF world title at Wrestlemania in 1990.

Warrior returned for the Hall of Fame induction last weekend after an 18-year split with the company.

WWE executive Triple H (Paul Levesque) said in an interview with ESPN that the return was a "bittersweet" experience after a lengthy reconciliation process between the two sides.

"The talent were so happy, Warrior was beside himself so excited, and I didn't see the smile come off his face all week. Then to have it just come to an end a day later is just shocking and tragic and devastating to all of us."
