On Friday, the Bengals placed wide receiver Tyler Boyd, cornerback Dre Kirkpatrick and linebacker Jordan Evans on injured reserve.
To fill their positions on the active roster, the team signed three players off the practice squad in running back Quinton Flowers, offensive tackle Kent Perkins and wide receiver Hunter Sharp.
Boyd, a third-year player, started the team’s first 14 games this season before suffering a knee injury in Game 14 vs. Oakland. He has 76 receptions for 1028 yards (both team highs) and seven touchdowns.
