Book (coach's decision) is inactive and has been deemed Philadelphia's emergency third quarterback Sunday versus Dallas.

Book was signed to the active roster Saturday after Jalen Hurts was ruled out for Week 17 due to a concussion. Kenny Pickett will be the Eagles' starting signal-caller Sunday, while Tanner McKee is set to work as his backup. Book will be able to enter the game only if both Pickett and McKee are unavailable due to injury, illness or ejection.
