No. 18 Iowa State (6-3, 5-2 Big 12, No. 16 CFP) at No. 13 Texas (7-3, 5-2, No. 15 CFP), 8 p.m. EST (Longhorn Network)
Line: Texas by 3.
Series record: Texas leads 13-2
WHAT'S AT STAKE?
Both teams are fighting for second-place in the Big 12 and a chance to slip into the conference championship game. Both need help to get there and neither can realistically afford to lose. Texas is seeking its eighth win, a mark it hasn't reached since 2013.
Texas DE Charles Omenihu against Iowa State QB Brock Purdy. Purdy is mobile and will present all kinds of run-option plays Texas must defend. Omenihu has to pressure Purdy in the pocket and keep him contained and turned inside when he wants to run. Purdy's decision making without RB David Montgomery (suspended in the first half) as an option or extra help in pass protection will be key.
PLAYERS TO WATCH
Iowa State: WR Hakeem Butler is a big playmaker. The 6-foot-5 Butler leads the nation with 22.7 yards a catch and has eight grabs of 40 yards or longer. He'll be facing a banged up Texas secondary that has been shredded in recent weeks.
Texas: Lil'Jordan Humphrey is the Longhorns' version of the big-body playmaker. He leads Texas with 63 catches for 947 yards and grabbed the winning touchdown with 20 seconds left to beat Texas Tech last week.
