5 key changes since the Buffalo Bills first matchup with the Miami Dolphins

Buffalo Bills will have Jordan Poyer and Rasul Douglas (and maybe Von Miller)

While the Buffalo Bills will be without two key parts of their defense they have a number of players who weren't available in Week 4 that will impact this game. The first player is Jordan Poyer, who missed Week 4 due to an injury.

He hasn't had the turnovers this season and if he doesn't have an interception or fumble recovery Sunday night, it will be the first season with the Bills without at least one. However, he has made an impact even without the turnovers and could be a difference-maker for this defense.

The second player is someone who wasn't even with the Buffalo Bills at the time of their first game as Rasul Douglas was traded for right at the trade deadline. The former Green Bay Packers cornerback has been an amazing addition to this defense and has certainly made up for Poyer's lack of turnovers with four interceptions and two fumble recoveries in eight games.

Finally, there is the question around Von Miller as he was still on the PUP list at the time of this game but did return the following week against the Jacksonville Jaguars. However, he has struggled this season after returning from an ACL injury and was a healthy scratch last week against the Patriots. If he is active, he will also be another player the Bills didn't have the last time these two teams met.
