NORMAN, Okla. (AP) — Iowa State coach Matt Campbell saw an opportunity to seize a win that would boost the Cyclones’ chances of reaching the Big 12 title game, so he put everything on quarterback Brock Purdy. His gamble failed. Parnell Motley intercepted Purdy’s two-point conversion pass with 24 seconds left, and No. 9 Oklahoma held off Iowa State 42-41 on Saturday night. And now, Iowa State’s conference title hopes are bleak.

Campbell went for the victory on the two-point try after Charlie Kolar caught a 13-yard touchdown pass to pull the Cyclones — down 42-21 in the second half — within one. Campbell said he didn’t regret going for two because Purdy already had passed for 282 yards and five touchdowns and rushed for 55 yards and another score.

Jalen Hurts passed for 273 yards and three touchdowns and ran for 68 yards and two more scores for the Sooners (8-1, 5-1 Big 12, No. 9 CFP). CeeDee Lamb had 167 yards and two touchdowns receiving and Kennedy Brooks ran for a season-high 132 yards to help Oklahoma bounce back from a loss to Kansas State two weeks ago. Oklahoma extended its November winning streak to 18 games and set up a showdown at league-leading Baylor next week. Breece Hall rushed for 110 yards for the Cyclones (5-4, 3-3).

All four of the Cyclones’ losses are by seven or fewer points. The Cyclones are a play here and there from a special season. UP NEXT: Iowa State hosts Texas on Saturday.
