WWE legendary wrestler Sid Eudy’s cause of death was revealed by his son, Gunnar Eudy, in a social media post.

“He was known as Psycho Sid Vicious to the world, but to our family, he was simply ‘Popper,’ the beloved grandfather,” Gunnar Eudy wrote on Facebook on Tuesday.

“Sid was diagnosed with congestive heart failure in 2016 and atrial fibrillation (better known as AFIB) around the same time. He was also given a pacemaker. In April 2021, he was diagnosed with stage 4 non-Hodgkin’s lymphoma, which was linked to Roundup weed killer. Although he never told anyone about his fight against cancer, Sid lived his life to the fullest, attending the gym, boxing classes, making appearances for his fans, and of course t-ball games for the kids.

“He passed away peacefully in his bed, leaving behind a legacy of strength and determination. I’ve never met anyone with a fraction of the strength as my father. He truly was one of a kind.”

On Monday, Gunnar Euday announced his father’s death.

Known as “Sycho Sid” and “Sid Justice,” he was “battling cancer for several years.”

Standing at 6-foot-9, he gained notoriety in 1989 when he signed with WCW and wrestled with and against some of the biggest names in the industry, including The Steiner Brothers, The Road Warriors and The Four Horseman.

He later competed in the World Wrestling Federation (WWF). Eudy became a six-time world champion, capturing the WWF Championship twice and the WCW World Heavyweight Championship twice.

He was a main-event fixture, starring in the headline matches of WrestleMania VIII and WrestleMania 13, two of WWE’s most iconic events. Perhaps his most memorable moments were when he clashed with Hulk Hogan at WrestleMania VIII in 1992 and his rivalry with The Undertaker at WrestleMania 13 in 1997.

Debuting as Sid Justice in WWE, he served as the Special Guest Referee at SummerSlam 1991, where WWE Champion Hulk Hogan and The Ultimate Warrior teamed up against The Triangle of Terror in a 3-on-2 Handicap Match. On the same night, he saved Randy Savage and Miss Elizabeth from an attack from Jake Roberts and The Undertaker at the couple’s newlywed reception.
