But should he?
If possible he is healthy enough to play, Smith should be on the field. He may only be able to be on the field for a few crucial plays, but any contribution from him would only be beneficial to a team and defense that is a game away from the Super bowl.
However, DE Ziggy Hood has played at a high level throughout the last few weeks, and had his best game last week against Baltimore. Smith is an elite player, but how effective will he be with so much rust to knock off?
Undoubtedly, Smith's return adds depth to the Steelers defensive line now.
But what do the Steelers do with him after the playoffs?
His contract expires after next season and he's had three season-ending injuries in the last four years. Hood has played well in Smith's absence and is ready to be a full-time starter.
Will the Steelers re-sign Smith for depth? Would Smith accept a smaller contract and a possible backup role?
It should be an interesting off-season, whether or not NFL games are played next year.
