at the Orange Bowl with an Oklahoma victory. The 1959 meeting is often considered Nebraska’s biggest upset ever. On that Halloween day, the unranked Cornhuskers defeated No. 19 Oklahoma 25–21 in Lincoln, ending the Sooners' 74-game conference win streak and their 16-game win streak over Nebraska. The 1963 matchup was almost canceled because of the assassination of President John F. Kennedy the day before, but ultimately both schools agreed to go ahead with the game. It was one of only five played that day (the others were Tulane-LSU, Texas Tech-Arkansas, Florida State-Auburn and Florida-Miami) as all others around the country were canceled. Former Nebraska head coach Bo Pelini served as an assistant at Oklahoma in 2004. End of the rivalry When the Big 8 Conference merged with Texas A&M, Texas Tech, Texas, and Baylor to form the Big XII, Oklahoma sided with the majority of conference members and voted against having an annual division-crossover rivalry game. The new conference was split into divisions, with Nebraska in the North and Oklahoma in the south, where they would play one another twice every four years. On June 11, 2010, the University of Nebraska announced that its regents had unanimously voted to end the university's affiliation with the Big 12 Conference, and would be joining the Big Ten Conference beginning with the 2011 season. The two teams met one final time in the 2010 Big 12 Championship Game before Nebraska joined the Big Ten, which Oklahoma won 23–20. In 2016, the schools announced a home-and-home series for 2029 and 2030.
