Karl Kassulke

Karl Otto Kassulke (March 20, 1941 – October 27, 2008) was an American professional football player.

Kassulke started in Super Bowl IV, where he and teammate Earsell Mackbee missed a tackle on Otis Taylor on the final touchdown of the game, late in the third quarter.

On July 24, 1973, Kassulke suffered a motorcycle accident on the way to training camp that left him paralyzed from the waist down.

Kansas City Chiefs coach Hank Stram, who was wired for sound by NFL Films executive producer Ed Sabol, noted the confusion in the Vikings' defense due to the Chiefs' shifting offense and quipped, "Kassulke was running around there like it was a Chinese fire drill".
