The Buffalo Bills have placed linebacker Baylon Spector on injured reserve due to a calf injury sustained during practice. This will sideline him for at least four games. Spector had been filling in for Terrel Bernard and was the primary backup to Dorian Williams, who is stepping in for the injured Matt Milano.

With Spector out, the Bills elevated receivers Tyrell Shavers and K.J. Hamler from the practice squad as they face potential receiver shortages due to injuries to Keon Coleman and Amari Cooper.
