ALLEN PARK — Defensive tackle Nick Fairley was placed on injured reserve on Wednesday to end his season.

 Fairley injured his shoulder at Green Bay and did not play at Arizona. He finished the season with 5.5 sacks and 35 tackles in 13 games.

 The Lions signed 26-year-old defensive tackle Ogemdi Nwagbuo, a former Michigan State Spartan. He has played in 35 games with the San Diego Chargers, who signed his as undrafted free agent in 2008, and the Carolina Panthers.

 At Wednesday’s practice, tight end Brandon Pettigrew (ankle) and Louis Delmas (knee) did not practice.

 The Lions (4-10) are preparing to play the Atlanta Falcons (12-2) on Saturday night. Kickoff is at 8:30 p.m. for the nationally televised game which replaces Monday Night Football.
