Riley Leonard passed for a touchdown, Jayden Harrison returned a kickoff 98 yards for a score, and Notre Dame’s defense made it hold up in a 23-10 victory over No 2 Georgia in the Sugar Bowl on Thursday that sends the third-ranked Fighting Irish into the semi-finals of the College Football Playoff.

In a game that was delayed by a day because of a deadly terror attack in the host city of New Orleans, Notre Dame (13-1, CFP No 5) made enough big plays and got some help from a clever move by coach Marcus Freeman.

Georgia (11-2, CFP No. 2) was in position to close within one score when Notre Dame stopped it on fourth-and-5 from the Irish nine-yard line with 9:29 to go.

Then, on fourth-and-short deep in his own territory, Freeman sent the punt team out before running all 11 players off the field and sending the offense out. Georgia raced to match up and then jumped offside as the play clock ticked down, giving the Irish a clock-sapping first down with 7:17 to go.

By the time the Bulldogs got the ball back, just 1:49 remained, and Notre Dame were well on their way to playing No 5 Penn State (13-2, CFP No. 6 seed) in a semi-final at the Orange Bowl in Miami on 9 January.

Georgia entered the game without starting quarterback Carson Beck, who injured his elbow in the Southeastern Conference championship game. He was replaced by Gunner Stockton, who was 20 of 32 for 234 yards and one touchdown.

Leonard finished with 90 yards passing and a team-high 80 yards rushing.

The game was tied at 3-all before Notre Dame scored 17 points in a span of 54 seconds.

The unusual sequence began with Mitch Jeter’s 48-yard field goal with 39 seconds left in first half.

Soon after, Georgia paid for an aggressive decision to attempt a drop-back pass from their own 25. RJ Oben’s blind-side sack caused Stockton to fumble at the 13, where Irish defensive lineman Junior Tuihalamaka recovered. Leonard found Beaux Collins over the middle for a touchdown on the next play for a 13-3 lead that stood at halftime.

By the time 15 seconds had elapsed in the third quarter, Notre Dame led 20-13.

Harrison took Georgia’s second-half kickoff all the way to the end zone, slipping a tackle near the middle of the field, cutting toward the right sideline and outrunning everyone.

Georgia closed the gap to 20-10 when Stockton hit reserve running back Cash Jones for a 32-yard score before Jeter’s third field goal of the game made it 23-10.
