The game determined the 2003 football champion of the Big 12 Conference.  The Oklahoma Sooners, winners of the South division of the Big 12, were upset by the Kansas State Wildcats, who won the North division, by a score of 35–7.  This was the second time the two teams met in the Big 12 Championship Game.  The first was the 2000 Big 12 Championship Game, a game in which Oklahoma won 27-24.

  Title: 2009 SEC Championship Game
  Passage: The 2009 SEC Championship Game was played on December 5, 2009, in the Georgia Dome in Atlanta, Georgia, to determine the 2009 football champion of the Southeastern Conference (SEC).  The game featured the Florida Gators and the Alabama Crimson Tide.  The Crimson Tide was the designated "home team"; this home team, chosen on an alternating basis, was 2–4 in SEC Championship Games.  The winner was all but assured to go on to play for a National Championship, in a likely matchup with the Texas Longhorns provided Texas won in the Big 12 Championship Game versus the north division champion Nebraska Cornhuskers.  Entering the 2009 contest, the SEC East was 11–6 in SEC Championship games, with the Florida Gators accounting for seven of the eleven victories.  Before the 2009 game, Alabama represented the SEC West six times in the conference championship game, compiling a 2–4 record, and had faced the Gators in all six of their previous SEC Championship game appearances.  This was the first and so far the only time any conference championship game had featured two undefeated teams and was also the first time an AP Poll No. 1 played a No. 2 outside of the BCS Championship Game since the top-ranked Ohio State beat the second-ranked Michigan during the 2006 regular season.
  Title: 2010 Big 12 Championship Game
  Passage: The 2010 Big 12 Championship Game was played at 7:00 p.m. on Saturday, December 4, 2010, at AT&T Stadium, then known as Cowboys Stadium, in Arlington, Texas to determine the 2010 football champion of the Big 12 Conference.  At that time, it was the final championship game for the conference as two members of the Big 12 had announced their intentions to leave the conference.  The South Division was represented by Oklahoma and the North Division was represented by Nebraska.  Oklahoma defeated Nebraska 23-20 to win the final Big 12 Championship and claim their seventh Big 12 Title.  It was Oklahoma's eighth appearance in the game.
  Title: 2009 Nebraska Cornhuskers football team
  Passage: The 2009 Nebraska Cornhuskers football team represented the University of Nebraska–Lincoln in the 2009 NCAA Division I FBS football season.  The Cornhuskers played their home games at Memorial Stadium in Lincoln, Nebraska and were led by head coach Bo Pelini.  The Cornhuskers finished the season 10–4, 6–3 in Big 12 and were Big 12 North Division champions and represented the division in the Big 12 Championship Game, where they lost to Texas 13–12.  Nebraska was invited to the Holiday Bowl, where they defeated Arizona 33–0.
  Title: 2005 Colorado Buffaloes football team
  Passage: The 2005 Colorado Buffaloes football team represented the University of Colorado at Boulder in the 2005 NCAA Division I-A football season.  The previous year's team won the Big 12 North Conference.  That marked the third Big 12 North championship for the Buffaloes in four years.  The team had expectations to improve on their winning and appeared to be on the right track with a 7–2 record to begin the season.  But in the end, head coach Gary Barnett had his contract bought out and Colorado suffered four straight losses including an embarrassing 70–3 loss to Texas in the Big 12 Championship Game.  They finished the season 7–6.  In the 2005 Champs Sports Bowl against Clemson, Mike Hankwitz acted as interim head coach, even though Dan Hawkins had been hired as the new head coach.  Hawkins coached his final game with Boise State in the game the day after Colorado played.

This was the first time the two teams met in the Big 12 Championship Game.  Texas A&M would not win the South Division again until the 2010 season, when they shared it with Oklahoma and Oklahoma State.  Kansas State went on to win the North in 2000 and 2003, when they also beat Oklahoma to capture their first conference title since 1934.
  Title: Nebraska–Texas football rivalry
  Passage: The Nebraska–Texas football rivalry was an American college football rivalry between the Nebraska Cornhuskers and Texas Longhorns.  The rivalry dissolved when Nebraska left the Big 12 Conference for the Big Ten Conference.  Due to Colorado, Missouri, Nebraska, and Texas A&M leaving the conference, the Big 12 Championship Game dissolved due to a lack of teams in the conference.  The last ever Big 12 Championship game was played between Nebraska and Oklahoma in 2010.
