On this day in 1967, the Green Bay Packers' hopes for a third straight NFL championship and a spot in Super Bowl II against the AFL champion Oakland Raiders were dashed in the so-called 'Ice Bowl' when the Dallas Cowboys scored a touchdown with less than a minute left in regulation to take a 24-21 lead; a field goal by the Packers tied the game at the end of regulation, but in overtime Dallas scored a field goal of their own to clinch a 27-24 victory and their first NFL title. One Green Bay player, offensive lineman Forrest Gregg, was so heartbroken over the defeat that he would retire from pro football permanently just two games into the 1968 NFL season.

Packers coach Vince Lombardi would later call the loss to Dallas the worst moment of his career; by contrast, Cowboys head coach Tom Landry would look back with pride on the way his team had bounced back against the odds to take down the Packers. The Cowboys' surprising triumph in the 1967 NFL title game was just the first of many such comeback playoff wins Landry would rack up before he retired in 1988.
