The Steelers are going with some extra bulk over the last portion of the 2013 season.
The team released linebacker Kion Wilson Saturday, making room for rookie defensive end Brian Arnfelt, who was undrafted out of Northwestern in 2013.
Arnfelt showed promise during training camp, and, along with Nick Williams (who's on injured reserve) sparked some optimism about the future depth along the defensive line.
It's unlikely he'll be active for Sunday's game against the Cincinnati Bengals, but with recent injuries to Brett Keisel (already ruled out for Sunday), Steve McLendon and Ziggy Hood, it could be a move in advance of placing Keisel on injured reserve (he's missed all but a few plays of the team's last four games) and bolstering the depth behind Hood.
The Steelers are all but eliminated from the playoffs, and may reach that point before kickoff. If throwing in the Terrible Towel isn't an option, getting some younger players some time with the first and second teams in practice isn't a bad idea.
