Three critical turnovers cost the Sooners in a 24-19 loss to Kansas State last September, and Oklahoma was tied with Notre Dame at 13 in the fourth before the Irish scored 17 straight points to run away with a 30-13 victory.
Even this season, Oklahoma narrowly escaped home wins over West Virginia (16-7) and TCU (20-17), both of which currently have 3-4 records.
The Sooner defense will face its most difficult challenge yet this season in a Texas Tech offense that ranks sixth in the nation with 548.1 yards per game, and has run over 100 plays in two of its last three games.
In their last game, the Red Raiders won 37-27 at West Virginia, which beat Oklahoma State at home this year and typically holds a strong home-field advantage.
“Definitely a good win,” Tech senior defensive lineman Kerry Hyder said of the 2011 victory in Norman. “But if you remember, we didn't finish too high after that. We take it one week at a time, and we look forward to the challenge of going up there and getting the win.
“We know the tougher environment, that's why this past week was so crucial for us being able to get a road win like that. So we definitely got some confidence brewing and we want to go in there and get a win.”
