The Broncos converted four out of five turnovers into 24 points as they eliminated the two-time defending Super Bowl champion Patriots, 27–13, and won their first playoff game since defeating the Atlanta Falcons in Super Bowl XXXIII. This game also ended New England's league-record ten-game postseason winning streak and gave quarterback Tom Brady his first ever postseason loss.
