IOWA CITY, Iowa -- Spencer Petras threw a 44-yard touchdown pass to Nico Ragaini to complete No. 3 Iowa's comeback from a two-touchdown deficit, No. 4 Penn State's offense did next to nothing after quarterback Sean Clifford was knocked out of the game and the Hawkeyes held on for a bruising 23-20 victory Saturday.
The Hawkeyes (6-0, 3-0) took control of the Big Ten West with their 12th straight win and thrust themselves into the College Football Playoff conversation.
Penn State (5-1, 2-1) lost for the first time in 10 games and headed back to Happy Valley with a list of injuries that could make its path through the rest of the season difficult.
When Petras took a knee in victory formation to end the game, students and other fans poured out of their end zone seats to celebrate. Bodies were packed together the entire width of the field from the south end zone to the 10-yard line on the other end.
Iowa chipped away with field goals by Caleb Shudak to cut it to 20-16. The winning drive started when it got the ball at the Penn State 44 with 6:35 left.
Petras rolled to his right and found Ragaini alone on the left side. Linebacker Curtis Jacobs knocked him out of bounds, but not before he got the ball over the goal line. All-America center Tyler Linderbaum was the first man to greet him in the end zone.
Penn State coach James Franklin didn't disclose the nature of Clifford's injury. He was hurt with the Lions leading 17-3 when he took a big hit from linebacker Jack Campbell, and he was out of uniform on the sideline in the second half.
After Ta'Quan Roberson took over for Clifford in the middle of the second quarter, Penn State managed just 50 yards on 46 plays the rest of the way.
No. 7 Ohio State 66, Maryland 17
COLUMBUS, Ohio -- C.J. Stroud threw five touchdowns passes as Ohio State scored on nine straight possessions.
Stroud was 24 for 33 for 406 yards and threw two touchdown passes each to star wideouts Chris Olave and Garrett Wilson against a depleted Maryland secondary before taking a seat after three quarters.
Freshman TreVeyon Henderson, after managing just 17 yards rushing in the first half, finished with 102 and two touchdowns. He also caught a 26-yard TD pass in the first half for the Buckeyes (5-1, 3-0 Big Ten).
Master Teague also had a touchdown plunge as Ohio State beat Maryland (4-2, 1-2) for the seventh consecutive time.
Taulia Tagovailoa was 28 for 39 for 279 yards and two touchdowns for Maryland but threw two late picks.
Boise State 26, No. 10 BYU 17
PROVO, Utah -- Hank Bachmeier threw for 172 yards and Boise State forced four turnovers in pulling the upset.
Cyrus Habibi-Likio ran for a season-high 75 yards and a touchdown, and Andrew Van Buren added a season-high 60 yards and a touchdown. The Broncos (3-3) snapped a two-game losing streak in the series.
Jaren Hall threw for a career-high 302 yards and a touchdown for BYU (5-1). Tyler Allgeier ran for 73 yards and a touchdown. The Cougars outgained Boise State 413-312.
No. 11 Michigan State 31, Rutgers 13
PISCATAWAY, N.J. -- Jalen Nailor caught touchdown passes of 63, 63 and 65 yards from Payton Thorne as the Spartans used their big-play offense to remain unbeaten.
Kenneth Walker, who came into the game leading all Football Bowl Subdivision players in rushing, ran for 233 yards, including a school-record 94-yard touchdown. It was the longest offensive play in Michigan State history.
Michigan State (6-0, 3-0 Big Ten) is off to its best start since it won its first eight games in 2015, when it reached the College Football Playoff.
Rutgers (3-3) lost its third straight, all against ranked opponents. The Scarlet Knights fell to No. 9 Michigan two weeks ago and No. 7 Ohio State last week.
Nailor finished with five catches for a career-best 221 yards, a stadium record. The old mark of 2007 was set by Larry Fitzgerald of Pittsburgh in 2003.
It was the fifth time in FBS history a team has had a 300-yard passer, a 200-yard rusher and a 200-yard receiver in the same game.
No. 19 Wake Forest 40, Syracuse 37, OT
SYRACUSE, N.Y. -- A.T. Perry caught three touchdowns, including a 22-yarder from Sam Hartman in the left corner of the end zone for the win.
A 38-yard field goal by Andre Szmyt gave Syracuse (3-3, 0-2 Atlantic Coast Conference) a 37-34 lead on its first possession in overtime, but the Demon Deacons (6-0, 4-0) scored six plays later to start 6-0 for the first time since 1944.
Sean Tucker scored on a 28-yard pass and run from Garrett Shrader with 21 seconds to go in regulation to tie the game after the Demon Deacons had taken a 34-27 lead just three minutes earlier on a 10-yard run by Christian Beal-Smith.
No. 24 SMU 31, Navy 24
ANNAPOLIS, Md. --Tanner Mordecai threw for 324 yards and two touchdowns as SMU rallied from a 14-point second-quarter deficit.
Bryan Massey scored on a 95-yard kickoff return to begin the comeback for the unbeaten Mustangs. SMU (6-0, 2-0 American Athletic Conference) had the game tied by halftime and went up 31-24 on a 22-yard TD pass from Mordecai to Jordan Kerley with 8:19 remaining in the final quarter.
Mordecai now has 26 touchdown passes on the season. He also threw a 66-yarder to Reggie Roberson on fourth-and-1 to open the scoring, but Navy (1-4, 1-2) answered with the next 21 points.
Chance Warren tied the game with a 23-yard scoring run, then Tai Lavatai threw the first touchdown pass of the season for the Midshipmen, 37 yards to Kai Puailoa-Rojas on a flea-flicker.

No. 22 Arizona State 28, Stanford 10
TEMPE, Ariz. -- Deandre Pierce scored a 27-yard touchdown on a lateral off an interception and Arizona State rode its explosive run game to a win over Stanford.
