The Patriots listed Josh Gordon on their injury report as questionable. That seems to indicate that they plan on playing the newly acquired receiver.
Nobody but the Patriots know how many snaps he will play in. It's unlikely anyone will be able to get that information out of them before Sunday's game.
Given the fact that he showed up to Patriots practice for the first time on Wednesday, it's highly unlikely that Gordon will see a ton of snaps. But that doesn't mean he can't make an impact with the time he does get.
It should be interesting to see how Bill Belichick uses his new weapon after a few days of practice.
