World Wrestling Entertainment performer Eddie Guerrero was found dead in his hotel room Sunday morning, according to Minneapolis police.

The 38-year-old professional wrestler didn't answer a wakeup call Sunday and didn't respond to a knock on his hotel-room door, according to newspaper reports. Security guards and Guerrero's nephew forced their way into his room and found the 5-feet-8, 220-pound wrestler on the floor, the Minnesota Star Tribune reported.

"This is a huge loss," WWE chairman Vince McMahon said in a statement. "Eddie was a giving, loving, fun-loving human being who had so much to give, he was a consummate performer who will be so missed by his fans."

Police said there are no signs of foul play or indications that Guerrero's death was a suicide, the Star Tribune reported. His death is under investigation.

Guerreo's nephew, fellow WWE performer Chavo Guerrero, said Guerrero had battled drug and alcohol abuse in the past but had celebrated four years of sobriety just days ago. He denied drugs or alcohol played a part in Guerrero's death.

Guerrero was in Minneapolis with 60 to 80 other wrestlers to film "Friday Night Smackdown" at the Target Center, according to the Star Tribune.

Guerrero became WWE champion in February 2004 and lost the title four months later.

The WWE said its show in Minneapolis on Sunday night would go on as a tribute to Guerrero.

A very sad day indeed.
