Avery Williamson is on the 53-man roster today. I don’t think that guarantees that he will be active for the game, however, especially in light of the fact that the Pittsburgh Steelers have elevated Antoine Brooks from the practice squad, and also activated two others to the 53-man roster in Jayrone Elliott and Trey Edmunds.
A veteran, experienced starting inside linebacker, Williamson just came over on Monday from the New York Jets in exchange for a fifth-round draft pick (with the Steelers also getting a seventh-round pick back as part of the deal). However, the team has made it clear that this wasn’t a move made with the idea that he would start.
