Karl Robert Sweetan (October 2, 1942 in Dallas, Texas – July 2, 2000, in Las Vegas, Nevada) was a professional NFL quarterback who played in five NFL seasons from 1966 to 1970 for 3 different teams. He is tied with several other players for the record longest pass completion (99 yards to Pat Studstill on October 16, 1966) against the Colts. However, the Lions lost 45-14 in front of 60,238 fans at Memorial Stadium in Baltimore, Maryland. It is notable that he was the first non-Redskins quarterback to accomplish this feat. He was the Lions starting quarterback during the filming of the movie Paper Lion. He also saw playing time in the Canadian Football League with the 1964 Toronto Argonauts. Sweetan also gained notoriety of sorts later when it was alleged that he tried to sell an NFL football playbook to another team; however, the charge was not proven.
