Norman, Okla. ? It’s time for Nebraska to take its final bow in the Big 12.

After decades of rivalries with teams across the Midwest, the Huskers will join the Big Ten next summer — but not before one last revival of their storied series against Oklahoma.

The question to be decided tonight at the new Cowboys Stadium in Arlington, Texas, is whether Nebraska will take the championship and run or leave after a second straight sour disappointment in the Big 12 title game.

The 13th-ranked Cornhuskers (10-2, 6-2 Big 12) have won the North in back-to-back seasons but lost the championship game to Texas last season on a field goal after one second was put back on the clock.

No. 10 Oklahoma (10-2, 6-2) is going after its seventh Big 12 title since 2000.

“OU and Nebraska have a rich tradition of playing each other for big games,” Sooners safety Quinton Carter said, “and I’m pretty sure this will go down in history as another big game.”

It was almost an annual rite for Oklahoma and Nebraska to be playing for the conference title on Thanksgiving weekend during the days of the Big Eight, when both were national powerhouses under Barry Switzer and Tom Osborne.
