NORMAN, Okla. (AP) — Parnell Motley intercepted Brock Purdy's two-point conversion pass with 24 seconds left and No. 9 Oklahoma held off Iowa State 42-41 on Saturday night.

Iowa State coach Matt 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.

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.

Purdy passed for 282 yards and five touchdowns and Breece Hall rushed for 110 yards for the Cyclones (5-4, 3-3)

Lamb put on a show in the second quarter. On his 62-yard touchdown reception, he caught the ball on the left sideline, then cut across to the opposite sideline. He lowered his shoulder through a defender to reach the end zone and push Oklahoma's lead to 28-7.

The Sooners seemingly took control with a 10-play, 97-yard drive in the third quarter. Brooks finished it with a 48-yard run that gave Oklahoma a 42-21 lead.

Purdy connected with Sean Shaw for a 33-yard touchdown to trim Oklahoma's lead to 42-35, then Hurts threw an interception to give Iowa State good field position and set up the final sequence.

Oklahoma plays at No. 11 Baylor on Saturday in a matchup that will affect the Big 12 title picture and could affect the College Football Playoff.
