“I am deeply saddened to share that my father, Sid Eudy, has passed away after a years-long battle with cancer. He was a man of strength, kindness and love, and his presence will be deeply missed,” Gunnar Eudy said in a Facebook post. “We appreciate your thoughts and prayers as we mourn this loss.”

A wrestling career that began in the late 1980s, Eudy was briefly a member of Ric Flair’s legendary stable “The Four Hourseman” before joining WWE, then known as the WWF, in 1991. With a bold, intense and unpredictable personality to match his stunning physique, Eudy quickly rose to prominence in the company, including a memorable appearance at the 1992 Royal Rumble that began a feud with Hulk Hogan. Eudy and Hogan would main event matches at WrestleMania 8 that same year at the Hoosier Dome in Indianapolis.

After leaving the company shortly thereafter, Eudy returned in 1995 and introduced his iconic “Sycho Sid” gimmick a year later. He would win the WWE Championship for the first time at Survivor Series 1996 after defeating Shawn Michaels. Eudy would win the title again in 1997, defending it against The Undertaker in the main event of WrestleMania 13, which The Undertaker won during his unprecedented WrestleMania streak. Eudy left WWE later that year. Eudy also had stints with WCW and suffered a devastating leg injury in 2001 that nearly ended his wrestling career. He made his final appearance with WWE in 2012.
