SOUTH BEND – Notre Dame opened the second half just how it needed to as the Irish lead Navy 24-20 entering the fourth quarter.
But Midshipmen quarterback Keenan Reynolds punched in a 4-yard touchdown run four seconds into the fourth quarter to put Navy up 27-24.
The Irish forced the Midshipmen to punt after six plays on the half's opening drive, then Notre Dame methodically drove 84 yards for a touchdown.
Tight end Ben Koyack ended the Irish drive with a 17-yard touchdown catch. The junior has three touchdowns on five receptions this year.
After giving up 207 rushing yards in the first half, Notre Dame gave up 93 rushing yards in the third quarter but it didn't give up any points.
Tommy Rees has thrown for 194 yards with two touchdowns and two interceptions for the Irish.
