Document 15: 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.
