The 49ers-Cowboys playoff history is a rich one from back-to-back conference title games in the early 1970s, the iconic “Catch” in the 1981 season and then the heated rivalry in the 1990s when the Cowboys won the first two meetings on the way to Super Bowl titles and then the Niners took the third game.
