In order to fill out the 53-Man Roster, the Patriots will call up Chris Barker from the practice squad. It is expected that he will dress for the game, because why call him up if you don't? Barker played mostly left tackle in the preseason, but is more of an interior OL than an OT. With the Patriots thin on the offensive line, particularly on the edges, this move gives them an emergency player in case the crap hits the fan.
Barker initially joined the Patriots in 2013 on a waiver claim and was stashed on the 53-man roster that season. He's bounced up and down from the practice squad, but hasn't seen a lot of meaningful action in the regular season. Right now, the Patriots have Cameron Fleming and Bryan Stork as their starting tackles, with each set to make their first career start at their current position. For Fleming, it's like playing Right Tackle in a mirror whereas with Stork you have a center playing tackle. Stork has good size to play anywhere on the OL and has previous experience as an emergency fill-in at tackle at Florida State.
As for the injury front, expect Marcus Cannon, Sebastian Vollmer, Jamie Collins, and Tre Jackson to be out. They haven't been able to participate in practice this week, although it's very possible all four will return next week. If the Patriots OL can get healthy, Barker will be waived after the game and sent back to the practice squad either during the week or after the conclusion of the Buffalo Bills game. We will find out if they are ruled out soon enough, depending on if they flew with the team to New Jersey.
