The Bills made a few roster changes on Wednesday morning.
Linebacker Matt Milano (leg) and defensive tackle DaQuan Jones (pec) were placed on the Injured Reserve list. Milano and Jones suffered injuries in last week's game against the Jaguars that require surgery.
The Bills signed linebacker A.J. Klein to the active roster. Klein started the season on the practice squad. This is the linebacker's fourth stint in Buffalo. He has started in 82 games and played in 144 throughout his 11-year career.
Buffalo will make another adjustment to the linebackers room as linebacker Baylon Spector is designated to return from Injured Reserve. Spector began the season on IR with a hamstring injury. The LB is in his second season with the Bills and played in six games during his rookie season.
Lastly, the Bills are signing defensive tackle Andrew Brown to their practice squad. Brown most recently played for the Chicago Bears. The DT has also played for the Chargers, Texans, Bengals and spent time on other teams' practice squads. He has played in 28 games and made one start in his five-year career.
Brown was originally drafted by the Bengals in the fifth round of the 2018 NFL Draft. He is from Chesapeake, Virginia and played collegiately at the University of Virginia.
