The 2005 Indianapolis Colts season was the franchise's 53rd season in the National Football League, the 22nd in Indianapolis and the fourth season under head coach Tony Dungy. The Colts improved on their 12–4 record from 2004 and finished the season 14–2. Indianapolis started the season with a 13-game winning streak and were heavily favored to go to and win Super Bowl XL. The Colts' rival, the New England Patriots, lost to the Denver Broncos in the Divisional round of the playoffs. The following day, the Colts were favored over the Steelers because they had easily beaten them in their previous meeting. However the Colts lost their first playoff game to the eventual Super Bowl champion Pittsburgh Steelers, when Placekicker Mike Vanderjagt missed a crucial field goal.
