During his weekly press conferences, Notre Dame head coach Brian Kelly maintained the same stance — it will be a game-time decision at quarterback for Saturday's matchup with North Carolina.

Well, it's officially game day. Here is what we are being told.

According to multiple sources, Irish247 has been informed that quarterback Ian Book will be the starter when the Fighting Irish take on the Tar Heels in Chapel Hill at 3:30 pm ET.

Quarterback Brandon Wimbush was seen Sunday on crutches and in a boot. Despite hvaing the boot off his foot early this week and no crutches to be found come Tuesday, we continue to hear that he'll only be used in an emergency role or if a change is needed. Wimbush, we're told, will be the No. 2 quarterback for Notre Dame, with Montgomery VanGorder listed at No. 3 on the depth chart.

Our intel was only strengthened late Friday night when Book's 7-on-7 coach from high school sent out a message on Twitter. "[Book] gets his first start tomorrow."

247Sports rated Book as the No. 17 pro-style quarterback in the country as a high school senior. He threw 30 touchdown passes to just five interceptions, while throwing for over 3,000 yards and at slightly above a 70-percent completion rate. He also rushed for nearly 800 yards in his final year.

Earlier this week, offensive tackle and captain Mike McGlinchey was asked about Book. He made it clear that once Book's name is called, he'll be ready. Well, barring a last second change, it looks like today's the day
