The Pittsburgh Steelers are hosting the Seattle Seahawks on Sunday and inside linebacker Vince Williams has already left the game in the first quarter with a hamstring injury. He is doubtful to return.
Williams opened the game wearing the Steelers communication helmet with the green dot on it.
Williams missed some time during training camp and preseason with a hamstring injury.
With Williams sidelined, the Steelers are left with healthy inside linebackers Mark Barron, Devin Bush, Ulysees Gilbert III and Tyler Matakevich.
The Steelers and Seahawks are scoreless with the first quarter winding down. The Steelers defense has registered three sacks so far in the game.
