NORMAN, Okla. (AP) - Oklahoma's scorched secondary is about to get tested again.
The 13th-ranked Sooners (9-2, 6-2 Big 12) gave up more than 450 yards passing to each of the top 10 passing teams they've faced this season, and they lost both times.
Next up is a road game Saturday night against No. 3 Oklahoma State (10-1, 7-1) and an offense that ranks second in the nation in passing behind quarterback Brandon Weeden and All-American receiver Justin Blackmon.
Coach Bob Stoops said Tuesday that Oklahoma's secondary must have "discipline and responsibility" and it would help if the Sooners could also get some pressure on Weeden.
However, he doesn't expect starting defensive end Ronnell Lewis to return after missing last week's game with a sprained ligament in his left knee.
