The Sooners are undefeated no more.

No. 5 Oklahoma suffered its first loss of the season after a 48-41 defeat on the road to Kansas State.

After a Wildcat touchdown at the start of the fourth quarter, the Sooners found themselves trailing 48-23 with 12:54 to go. Oklahoma then mounted a furious comeback which saw it roar back to within seven points with 1:45 left.
