Smith-Njigba was limited at Wednesday's walkthrough due to a knee injury, John Boyle of the Seahawks' official site reports.
Smith-Njigba consistently has earned a snap share of at least 60 percent per game since the Seahawks' Week 5 bye, recording a 47-540-3 receiving line on 66 targets over the last 11 contests. The rookie first-round pick has yet to break through with the first signature performance of his career, though, which isn't a shock on a team that stresses the run game and also features veteran wide receivers DK Metcalf and Tyler Lockett. Smith-Njigba will now have to work his way past a health concern in order to suit up Sunday versus the Steelers.
