He and Paul Hornung were both suspended for the entire 1963 season for betting on NFL games. I've never read of any allegations that they bet against their teams. I read an article earlier today that quoted Lions linebacker Wayne Walker as saying both he and Karras bet on the Packers in the 1962 NFL championship game against the Giants because, having played both teams, they were certain Green Bay would clobber the Giants--that even though the Lions has mauled the Packers on Thanksgiving for Green Bay's only loss that season.
Anyway, although there have been claims that other players also bet on NFL games, only Hornung and Karras were suspended. They were both reinstated in 1964. Hornung reportedly was contrite; he later was inducted into the Hall of Fame. Karras was reportedly, well he reportedly was Alex Karras, which didn't endear him to Pete Rozelle; he has never been inducted.
