The Saints are preparing to have third-string quarterback Ian Book start at quarterback this week vs. the Dolphins, according to NFL Network's Tom Pelissero and Ian Rapoport.
It will be Book's first-career start.
The decision comes as quarterbacks Taysom Hill and Trevor Siemian are both expected to be placed on the reserve/COVID-19 list.
Book was a fourth-round pick of the Saints in the 2021 NFL draft. He joined New Orleans after a successful college career at Notre Dame.
There, he became Notre Dame's all-time leader in wins as a starting quarterback, leading the Fighting Irish to two College Football Playoff appearances.
