The quarterback depth chart has trimmed from four to two for the New England Patriots.
The organization released Ian Book from the practice squad and waived Matt Corral off the exempt/left squad list on Monday, as first reported by Doug Kyed of the Boston Herald.
Book, 25, worked out and signed with New England last week. The Notre Dame product entered the NFL in the fourth round of the 2021 draft at No. 133 overall. Making previous stops with the New Orleans Saints and Philadelphia Eagles, he has started his lone career game beyond the preseason.
