Clint Longley, a rookie in 1974, came into a Thanksgiving Day game when Staubach was knocked out. The score was 16-3 Redskins in the third quarter.
If Dallas lost they would face elimination from the play-offs.
Late in the 4th the score was 23-17 and Longley hit Pearson for a 50-yard pass with 28 seconds left to win 24-23.
After the game Blaine Nye was quotes as saying of the Longley performance that it was "the triumph of the uncluttered mind."
