Running back Le'Veon Bell is listed as out for Saturday's AFC Wild Card game against the Cincinnati Bengals coming off a foot injury he suffered against the Cleveland Browns last week.
With Williams out, look for Fitzgerald Toussaint and Jordan Todman to carry the load for the offense. Toussaint stepped in against the Browns last week, and there is plenty of confidence in the young back.
"He is a diligent worker," said Coach Mike Tomlin of Toussaint. "He brings a business-like approach. I think he's one of those guys that everybody is excited about seeing play. They are excited about seeing him get an opportunity, because he's a guy that doesn't say much. He's extremely low maintenance.
"He really works hard to put himself in position to be a positive asset or contributor to us when given the opportunity."
Toussaint, who was activated off the team's practice squad on Nov. 27 takes pride in that work ethic.
"I go out there every day and put it all on the line," said Toussaint, who carried the ball 18 times for 42 yards in the regular season. "I feel like every moment is a big opportunity for me to go out there and show what I have. That is what I plan to do.
"I have to be ready to take on the task."
Out: RB DeAngelo Williams (foot).
Probable: S Robert Golden (not injury related), WR Martavis Bryant (neck), CB William Gay (not injury related), LB William Gay (not injury related), TE Ben Roethlisberger (not injury related), LB Vince Williams (illness).
