The Bills signed Ateman to their practice squad Thursday, Alec White of the team's official site reports.
Ateman signed with the Bills this offseason and spent training camp with the team. He was cut Tuesday but will now be back to provide depth to Buffalo's pass-catching corps. Ateman last recorded an NFL reception in 2019 as a member of the Raiders but put together a solid spring with the XFL's St. Louis Battlehawks.
