Nebraska and Oklahoma will renew one of college football's greatest rivalries for two seasons.

The schools announced Thursday they have signed a contract that will have the Cornhuskers and Sooners play in 2021 in Norman, Okla., and in 2022 in Lincoln, Neb.

Nebraska athletic director Tom Osborne said the schools have a tradition of playing ``with great intensity on the field, but with a great deal of respect from both sides and among the fan bases.''

Oklahoma athletic director Joe Castiglione said it was important to both fan bases to ``rekindle a fabled series between two tradition-rich programs.''

The teams played 71 straight seasons as members of the Big Six and Big Eight. The game decided the old Big Eight championship 31 times in 36 seasons.
