Philadelphia’s matchup with Dallas on Sunday may be impacted by injuries and concussions affecting key players. Quarterback Jalen Hurts remains in the concussion protocol, and backup Kenny Pickett is dealing with a rib injury. To address these concerns, the Eagles have signed Ian Book to their practice squad. If both Hurts and Pickett are unable to play, Tanner McKee and Book will be available to lead the offense against the Cowboys.
Hurts was forced out of action in Week 16’s loss to Washington due to a concussion, allowing Pickett to take over and lead the team to a touchdown pass. However, Pickett sustained his own injury and struggled during preseason competitions with McKee for the backup job. If Hurts clears protocol soon, Pickett is likely to start; otherwise, Eagles fans may need to prepare for McKee leading the offense.
