The Pittsburgh Steelers promoted defensive end Brian Arnfelt from the practice squad to the active roster.
The Steelers released linebacker Kion Wilson, who played in seven games with two starts.
Arnfelt is a 6-foot-4, 298-pound undrafted free agent from Northwestern.
He has spent the entire season on the practice squad.
The Steelers ruled out defensive end Brett Keisel for Sunday night's game against the Cincinnati Bengals due to a foot injury.
