an Book started at quarterback for No. 8 Notre Dame in its game against Wake Forest on Saturday.
The redshirt sophomore replaced Brandon Wimbush in the starting lineup, two days after coach Brian Kelly sidestepped questions about making a change at the position.
The Fighting Irish (3-0) won their first three games by a total of 20 points and didn't score more than 24 points in any of those games.
Notre Dame scored on its first possession in each of its first three games this season under Wimbush -- with two touchdowns and a field goal -- but failed to score on the first drive Saturday with Book.
