Baylon Spector
The other key injury on the defensive side of the ball worth watching ahead of Monday's game is linebacker Tyrel Dodson. He has been able to practice more than Douglas with two limited practices on Wednesday and Friday but did sit out Thursday as he is dealing with a shoulder injury.
If Dodson is not able to play then Baylon Spector should be the one to get the start as he replaced Dodson in the lineup after the injury against the Dolphins. He would play very well in his first extended snaps on defense this season and four total tackles.
Even if Dodson does play, Spector could still have a role in this game as the Bills could look to play more 4-3 defense than their standard nickel formation. The Steelers strength of their offense is the run game and they try to wear defenses down with the duo of Najee Harris and Jaylen Warren.
It could require the Bills to have bigger players in the box and having Spector as that third linebacker could make sense.
