Context paragraphs:
2003 Big 12 Championship Game: The 2003 Big 12 Football Championship Game was played on December 6, 2003 in Arrowhead Stadium in Kansas City, Missouri.  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.

2010 Big 12 Championship Game: 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.

Nebraska–Oklahoma football rivalry: The Nebraska–Oklahoma football rivalry was an American college football rivalry between the Nebraska Cornhuskers football team of the University of Nebraska and Oklahoma Sooners football team of the University of Oklahoma.  The rivalry continued in the Big 12 Conference until 2010, though the rivalry was more prominent when both teams were members of the former Big Eight Conference before 1996.  The annual rivalry effectively ended when Oklahoma was lined up in the Southern division of the newly formed Big 12 to maintain its rivalry with Texas and also its recruiting hotbeds in Texas.  As both teams won their respective divisions in 2010, they met in the 2010 Big 12 Championship Game.  Following the 2010 season, Nebraska left the Big 12 for the Big Ten Conference.  As a result, the 2009 meeting turned out to be the last regular-season scheduled meeting.  Nebraska's departure left the future of the rivalry in doubt.  The two teams have agreed to play a home-and-home non-conference series scheduled for 2021 in Norman (to celebrate the 50th anniversary of the 1971 classic) and 2022 in Lincoln.  They added games in 2029 and 2030 as well.

2000 Big 12 Championship Game: The 2000 Big 12 Football Championship Game was played on December 2, 2000 in Arrowhead Stadium in Kansas City, Missouri.  The game determined the 2000 football champion of the Big 12 Conference.  The Oklahoma Sooners, winners of the South division of the Big 12, narrowly beat the Kansas State Wildcats, who won the North division, by a score of 27-24.  This was the first time the two teams met in the Big 12 Championship Game, as they would meet again in the 2003 edition.

2009 Nebraska Cornhuskers football team: 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.

2009 Big 12 Championship Game: The 2009 Dr Pepper Big 12 Championship Game was held on December 5, 2009 at Cowboys Stadium in Arlington, Texas.  The divisional winners from the Big 12 Conference squared off in the 14th edition of the game.  The Texas Longhorns represented the South Division and the Nebraska Cornhuskers represented the North.  Texas won 13–12 on a last second field goal by placekicker Hunter Lawrence.

Nebraska–Texas football rivalry: 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.

1998 Big 12 Championship Game: The 1998 Big 12 Championship Game was played on December 5, 1998, at The Trans World Dome in St. Louis, Missouri, United States.  The game determined the 1998 football champion of the Big 12 Conference.  The Texas A&M Aggies, winners of the South Division of the Big 12, narrowly beat the Kansas State Wildcats, who won the North division, by a score of 36–33 in double overtime.  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.

Big 12 Championship Game: The Big 12 Championship Game is a college football game held by the Big 12 Conference.  The game was played each year since the conference's formation in 1996 until 2010 and will return starting with the 2017 season.  From 1996 to 2010 the championship game pitted the Big 12 North Division champion against the South Division champion in a game held after the regular season was completed.  From 2017 onward, the game will feature the two teams with the best records within the conference.

2009 SEC Championship Game: 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.
