IOWA CITY, Iowa (AP) — Aidan O’Connell threw for 375 yards and accounted for three touchdowns, David Bell had a career-best 240 yards receiving and Purdue continued its recent mastery over No. 2 Iowa with a 24-7 victory Saturday.

The Boilermakers (4-2, 2-1 Big Ten) have won four of their last five games against the Hawkeyes (6-1, 3-1). The loss ended Iowa’s 12-game winning streak.

Purdue beat its highest-ranked opponent on the road since 1974 at No. 2 Notre Dame. It was the second time in four seasons Purdue has knocked off a No. 2-ranked team. The Boilermakers won at home over a second-ranked Ohio State in 2018.

O’Connell was 30-of-40 passing with two touchdowns and ran for a score. He got the most work on a day when Purdue used backup quarterbacks Jack Plummer and Austin Burton in select situations. All three were in on different plays during the Boilermakers’ first-quarter drive that ended with O’Connell’s 6-yard touchdown run for a 7-0 lead.

O’Connell threw a 3-yard touchdown pass to TJ Sheffield in the final minute of the first half to give Purdue a 14-7 halftime lead. He threw a 21-yard TD pass to Bell in the fourth quarter. Bell had 11 receptions. He has a combined 37 catches for 558 yards and five touchdowns against Iowa in three seasons.

In other key games Saturday:

NO. 1 GEORGIA 30, NO. 11 KENTUCKY 13

With Georgia playing its first game as the nation’s No. 1-ranked team since 2008, Stetson Bennett threw three touchdown passes and the Bulldogs got another stifling defensive effort to beat Kentucky.

Bennett, starting his third straight game in place of injured JT Daniels, hooked up with freshman tight end Brock Bowers on a pair of scores.

The senior quarterback was 14 of 20 for 250 yards in another solid performance with Daniels watching from the sideline for the Bulldogs (7-0, 5-0 Southeastern Conference).

NO. 3 CINCINNATI 56, UCF 21

Jerome Ford rushed for a career-high 189 yards and four touchdowns, helping Cincinnati roll past UCF.

Desmond Ridder passed for 140 yards and a touchdown to help the Bearcats (6-0, 2-0 American Athletic Conference) extend the nation’s second-longest home winning streak to 24 games.

NO. 4 OKLAHOMA 52, TCU 31

Caleb Williams had a big starting debut for Oklahoma, throwing for 295 yards and four touchdowns and running for another score in the Sooners’ victory over TCU.

The freshman from Washington, D.C., unseated Spencer Rattler as the starter after leading a comeback victory over Texas last week in Dallas. He started fast against TCU with an opening 75-yard touchdown drive that took just under three minutes. Oklahoma (7-0, 4-0 Big 12) had three consecutive touchdown drives to open the third quarter, including two touchdown connections between Williams and receiver Jadon Haselwood.

NO. 5 ALABAMA 49, MISSISSIPPI STATE 9

Bryce Young threw for 348 yards and four touchdowns and Alabama rebounded from a loss to rout Mississippi State.

A week after falling at Texas A&M, Alabama (6-1, 3-1 Southeastern Conference) had 543 yards of total offense and the Crimson Tide had seven sacks. Alabama converted 12 of 16 third-down opportunities.

NO. 12 OKLAHOMA STATE 32, NO. 25 TEXAS 24

Tanner Brown’s fourth field goal gave No. 12 Oklahoma State its first lead and Spencer Sanders’ scrambling 10-yard touchdown run with 2:18 to play capped a victory over Texas to keep the Cowboys undefeated.

Texas built leads of 17-3 and 24-13 behind three touchdowns from Bijan Robinson before Oklahoma State’s defense and punishing run game behind Jaylen Warren took over for the Cowboys (6-0, 3-0 Big 12).

NO. 10 MICHIGAN STATE 20, INDIANA 15

Matt Coghlin’s 51-yard field goal to open the second half gave Michigan State the lead and Payton Thorne’s 12-yard touchdown pass provided the margin the Spartans needed to hold off Indiana.

The Spartans (7-0, 4-0 Big Ten) will remain atop the conference’s East Division at least two more weeks after reclaiming the Old Brass Spittoon.

AUBURN 38, NO. 17 ARKANSAS 23

Bo Nix threw for 292 yards and accounted for three touchdowns, Auburn’s defense contributed a touchdown and a key fourth down stop in the third quarter and the Tigers beat Arkansas.

Auburn (5-2, 2-1 Southeastern Conference) won its sixth straight in the series and handed Arkansas (4-3, 1-3) its third straight loss.

LSU 49, NO. 20 FLORIDA 42

Tyrion Davis-Price ran for an LSU-record 287 yards and had three touchdowns and the Tigers’ banged-up defense came up with four interceptions against Florida.

The stirring performance produced thunderous roars from a Death Valley crowd that came in with low expectations after unranked LSU (4-3, 2-2 Southeastern Conference) dropped its previous two games against Auburn and Kentucky, fueling speculation coach Ed Orgeron’s hold on his job was tenuous at best.

NO. 22 NORTH CAROLINA STATE 33, BOSTON COLLEGE 7

Devin Leary scrambled free and threw a jump pass to Thayer Thomas, who took it 79 yards for a touchdown to help North Carolina State run away from Boston College in Chestnut Hill.

Leary threw for 251 yards and three touchdowns, also completing a 40-yard scoring pass on the opening drive on a throw that bounced off the back of the defender before Devin Carter gathered it in.
