Steelers linebacker Ryan Shazier was listed as questionable for Sunday’s game because of a knee injury, but he got the green light to play in Seattle.
A different injury has Shazier questionable to remain in the game until the final whistle, however. Shazier has returned to the locker room with Steelers medical personnel in the second quarter of the game.
Shazier looked dazed on his way back to the locker room for what appeared to be a concussion evaluation and the Steelers quickly confirmed that was the case. Vince Williams took over for Shazier in the Pittsburgh defense.
Tight end Heath Miller also went to the locker room for the Steelers, but he’s expected to return after suffering a rib injury.
The Steelers lead 10-7 after a 10-yard run by Martavis Bryant on an end around put the Steelers back on top in the second quarter.
UPDATE 5:39 p.m. ET: Miller has returned to the game with the Steelers trailing 14-10 with two minutes left in the half.
