Smith-Schuster (knee) is considered questionable for Sunday's game against the Cardinals, Missi Matthews of the Steelers' official site reports.
James Conner (shoulder) is also in that category, but has a better chance of practicing Wednesday than Smith-Schuster, according to coach Mike Tomlin. If Smith-Schuster ends up limited or out this weekend, James Washington, Diontae Johnson and Tevin Jones would be in line to head the Steelers' Week 14 wideout corps.
