Former WWE and WCW superstar Vader passed away last night after a two-year battle with congestive heart failure. He was 63.

Vader’s son broke the news on social media, saying, “Around a month ago my father was diagnosed with a severe case of pneumonia. He fought extremely hard and clinically was making progress. Unfortunately, last night his heart had enough and it was his time.”

Vader had undergone open-heart surgery back in March and seemed to be doing well, but his health took a turn for the worse and he wasn’t able to recover.

Before his wrestling career, Vader – whose real name was Leon White – was a football star at the University of Colorado, where he was a two-time All-American offensive lineman.

He was drafted by the Rams in the third round of the 1978 NFL Draft and played in Super Bowl XIV against the Pittsburgh Steelers.

As a pro wrestler, Vader was a huge star globally – he was a three-time WCW heavyweight champ. In WWE, he battled guys like The Undertaker and Kane. He also made TV appearances on shows like “Baywatch” and “Boy Meets World.”
