The Niners would go down the field to score with 1:45 remaining. The game appeared over after Tramaine Brock appeared to have an interception. However, the interception was reviewed, and after review, the call was overturned, because replay concluded that the ball had hit the ground before Brock was able to control it. The next play, Kenneth Acker was called for pass interference which gave the Giants the ball on the goal line. Larry Donnell would catch the game-winning touchdown with 21 seconds left to give New York the win.
Question: HOw many seconds were left when Donnell won for New York?
Answer: 21
