Garrett Nussmeier threw a tying touchdown pass in the final seconds of regulation and hit Kyren Lacy for a 25-yard scoring strike on No. 13 LSU’s first play of overtime, completing a stunning 29-26 comeback victory over No. 9 Mississippi on Saturday night in Baton Rouge, Louisiana.

The winning score marked the first time LSU (5-1, 2-0 Southeastern Conference) led the entire game and fans streamed onto the field to celebrate a triumph that for now will put the Tigers back in the College Football Playoff discussion.

Nussmeier struggled much of the game, and threw two interceptions, but came alive when it mattered to finish with 337 yards and three TDs passing. Two of those touchdowns came on the last two snaps he took.

Jaxson Dart passed for 284 yards and a score, and Ulysses Bently IV ran for a 50-yard touchdown on a fourth-down play for Mississippi (5-2, 1-2), which suffered a serious blow to its hopes for winning a conference crown or earning a CFP bid.

No. 5 GEORGIA 41, MISSISSIPPI ST. 31 >> Carson Beck passed for a career-high 459 yards and three touchdowns and the host Bulldogs withstood the visiting Bulldogs’ second-half comeback bid for a win.

Georgia (5-1, 3-1 Southeastern Conference) played at times as if it were looking ahead to next week’s visit to No. 1 Texas but had enough offense for its 28th consecutive home win.

Georgia led 34-10 early in the second half before freshman quarterback Michael Van Buren Jr., making his second start, led the Bulldogs (1-5, 0-3) to two straight touchdowns. Van Buren’s strong performance was not enough to prevent Mississippi State’s fifth consecutive loss.

NO. 8 TENNESSEEE 23, FLORIDA 17, OT >> Dylan Sampson scored on his third touchdown of the game on a 1-yard run in overtime to give the host Volunteers a victory over the Gators.

Tennessee (5-1, 2-1 Southeastern Conference) went to overtime for only the second time. The first was in 1998 when it won the national title.

Trey Smack missed a 47-yard field goal try for Florida (3-3, 1-2) on the first overtime possession.

The Gators tied it with 29 seconds left on DJ Lagway’s 27-yard touchdown pass to Chimere Dike. After lining up for a 2-point conversion, Tennessee called a timeout and Florida kicked the extra point.

Sampson rushed for 112 yards.

NO. 10 CLEMSON 49, WAKE FOREST 14 >> Cade Klubnik passed for three touchdowns and Phil Mafah added two short touchdown runs as the visiting Tigers rolled past the Demon Deacons for their fifth straight win.

Clemson (5-1, 4-0 Atlantic Coast Conference) turned a couple of interceptions into touchdowns as it started to pull away with a 28-point second quarter.

Klubnik threw for 309 yards on 31 for 41 passing and Mafah gained 118 yards on 20 carries.

The Tigers threw in some wrinkles, with receiver Antonio Williams throwing 28 yards to tight end Jake Briningstool for a third-quarter touchdown.

Wake Forest (2-4, 1-2) dropped its fourth consecutive home game.

NO. 11 NOTRE DAME 49, STANFORD 7 >> Riley Leonard threw three touchdown passes and ran for another score to lead the host Fighting Irish (5-1) to a win over the Cardinal (2-4).

Leonard was 16 of 22 passing for 229 yards and three scores, and rushed six times for 31 yards and a TD.

The game was stopped at the end of the third quarter due to lighting in the area, with Notre Dame ahead 42-7. Play resumed after a delay of about an hour.

Steve Angeli replaced Leonard at quarterback when play resumed.

NO. 11 IOWA STATE 28, WEST VIRGINIA 16 >> Carson Hansen rushed for three scores, Rocco Becht threw a touchdown pass and the visiting Cyclones, who are tied with Notre Dame or the No. 11 ranking, beat the Mountaineers (3-3, 2-1 Big 12).

Iowa State (6-0, 3-0) opened the season with six wins for the first time since 1938.

The Cyclones are tied with Notre Dame for the No. 11 ranking.

NO. 14 BYU 41, ARIZONA 19 >> Jake Retzlaff passed for 218 yards and two touchdowns and the host Cougars forced four turnovers in a win over the Wildcats.

Darius Lassiter had 86 yards on five catches and Parker Kingston caught a touchdown pass and threw for a score on a trick play for BYU (6-0, 3-0 Big 12).

Noah Fifita threw for 275 yards and a touchdown to lead Arizona (3-3, 1-2 Big 12). But, he tossed three interceptions and lost a fumble.

NO. 21 MISSOURI 45, MASSACHUSETTS 3 >> Tigers receiver Luther Burden scored on a 61-yard jet sweep less than a minute into the game, and visiting Missouri (5-1) went on to beat the Minutemen in noncoference action.

UMass (1-6) lost its third straight game.

NO. 22 PITT 17, CALIFORNIA 15 >> Desmond Reid ran for 120 yards and two touchdowns and the host Panthers held off the Bears.

Pitt improved to 6-0 (2-0 ACC) for the first time since 1982 by relying on a defense that racked up six sacks on a day its revamped offense struggled.

Still, Pitt hung on as Cal (3-3, 0-3 ACC) let a couple of late opportunities slip away. Ryan Coe’s go-ahead 40-yard field goal attempt with 1:54 left was a low wobbler that sailed wide right.

Friday’s late result

ARIZONA STATE 27, NO. 16 UTAH 19 >> Cam Skattebo ran for 158 yards and two touchdowns and the host Sun Devils (5-1, 2-1 Big 12) spoiled Utes quarterback Cameron Rising’s return with a victory over Utah (4-2, 1-2). Rising threw three interceptions after missing three games with a finger injury.
