Ian Book: Everything you need to know

The Eagles re-signed Book to the practice squad Thursday. Philadelphia had waived Book on Tuesday, but he now reunites with the team as an emergency depth option at quarterback. With Jalen Hurts (concussion) and Kenny Pickett (ribs) unavailable for the Eagles' regular-season finale, Book got a chance to work as the team's top backup behind Tanner McKee against the Giants, though he didn't ultimately play any snaps. Hurts and Pickett are both working to gain clearance in time for Sunday's wild-card contest versus the Packers.

The Eagles waived Book on Tuesday. Book was signed to the Eagles' practice squad Dec. 26 before being signed to the active roster two days later due to injuries to Jalen Hurts (concussion) and Kenny Pickett (ribs). Book ended up serving as the Eagles' backup quarterback behind Tanner McKee against the Giants on Sunday, though the former didn't play a snap in the regular-season finale. Book could be back on the practice squad in case Hurts is unable to clear the league's concussion protocols in time for Sunday's wild-card round game against the Packers.

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.
