Former WCW wrestler Silver King, who also starred in the 2006 comedy "Nacho Libre" with Jack Black, died Saturday night in the ring ... and a kick may have triggered the coronary.
Silver King was playing his tried-and-true role of villain in London at the Roundhouse when he suffered a heart attack, collapsing and dying. Authorities say he died at the venue.
In the video, you see him get knocked down 3 times, kind of writhing on the ground look somewhat dazed. It doesn't really look odd -- just doing what wrestlers do when they choreograph matches.
