Delaware's defense opened the scoring by forcing a punt which resulted in a muffed snap that went over the Richmond punters head in the end zone. The punter kicked the ball out of the back of the end zone to prevent a Delaware touchdown, and UD took a 2–0 lead. On the ensuing drive the Blue Hens managed to get into field goal range and made the score 5–0.

Richmond again managed to get down the field and the Delaware defense again held them to a field goal, putting Richmond ahead 16–15. After defensive stops by both teams, the Richmond punter muffed a punt that failed to cross the 50.

The drive had initially stalled and kicker John Striefsky had missed a 42-yard field goal attempt wide left, however, the Delaware State Hornets were called for a personal foul on the play, giving UD 15 yards and a first down. The Hornets answered by driving down the field themselves, but had to settle for a 42-yard field goal by kicker Riley Flickinger, a career long. After trading punts several times and a 44-yard field goal attempt by Delaware State missed wide right, the Blue Hens were able to move the ball to the 1-yard line with 1.5 seconds left in the first half. The Blue Hens decided to go for the touchdown and the Hornets made a goal line stop as time expired in the first half with the aid of a questionable call by the officials. In the second half the offenses again moved the ball up and down the field but were still unable to punch it in for a score, with Delaware State reaching the Blue Hens 18-yard line before an interception.

Delaware State again moved into Blue Hens territory for the third straight time, but again turned the ball over as a fumble by Jason Randall on the Delaware 25-yard line was recovered by UD and returned to the 41. The Hens then drove down the field on five plays ending with a Pat Devlin 17-yard touchdown pass to freshman Rob Jones, increasing the lead to 21–7. Delaware State attempted to answer back, driving down the field into scoring range only to turn the ball over again after a Flickinger's 35-yard field goal attempt was blocked. Delaware State finally got a break, however, as on the ensuing drive Pat Devlin's pass went off the hands of a receiver and was intercepted by free safety Jerome Strums who raced 71 yards down the field for the Hornets first touchdown, cutting into the lead 21–10. After an excellent kickoff return, UD needed just 3 plays to pick up 23 yards for another touchdown as Leon Jackson rushed for a 3-yard touchdown making it 27–10 with 3:36 left in the game.
