Notre Dame defeated Navy, 54-27, in their first meeting in Dublin. The Fighting Irish also bested the Midshipmen, 50-10, in 2012. Officials are expecting 35,000 fans to flood Aviva Stadium in Dublin for the Aug. 29, 2020, game.

Book played in 13 games for Notre Dame during the 2019 season. He passed for 3,039 yards and 34 touchdown passes against just six interceptions. He was listed as the No. 11-best draft-eligible quarterback to watch for before the season started, according to NFL Network's Daniel Jeremiah.
