Prescott has been nursing a shoulder injury, which he suffered a couple of weeks ago. Garrett remains optimistic that he will be back in time for Week 17, via Grant Gordon of NFL.com:
“Last week, we really took it day by day, and this week we'll do the same thing,” Garrett said. “Obviously, he was able to play in the ballgame. Hopefully, we can get him on the same path where he's able to go on Sunday.”
Prescott has not been able to get much activity during practice this week. That was the case heading into Week 16 as well, but he was ultimately able to suit up. His recent lack of participation is likely just Dallas doing what it an to take a cautious approach with his recovery.
The Cowboys had been in control of their playoff destiny heading into their NFC East divisional showdown with the Philadelphia Eagles in Week 16; however, they ultimately fell short thanks in large part to Prescott's underwhelming play. As a result, there is now plenty of speculation regarding the severity of his injury going into the offseason.
For now, Dallas will need the stars to align for them to get into the playoffs by beating Washington and hoping that the New York Giants can somehow find a way to pull off the upset at home against the Eagles.
