In Super Bowl XLII, Blackburn had a costly penalty on a punt return as he was the extra man on the field on a 12-man-on-the-field penalty. After the play, New England Patriots head coach Bill Belichick challenged the play that the Giants had 12 men on the field and won. The penalty resulted in a first down, but the Patriots did not score on that drive after a failed 4th down conversion. As a result, the Giants improved their field position by 20 yards, so the penalty actually benefited the team. The Giants went on to win the game.
