The Bills are bringing back a familiar face as the team announced Thursday they are signing LB A.J. Klein to the practice squad.
Klein was claimed off waivers by the Bills last November and appeared in six games.
The 32-year-old linebacker did not make the team's 53-man roster to begin the 2023 season but has been brought back ahead of Week 3.
In a corresponding move, LB Christian Kirksey has announced he plans to retire.
