Roethlisberger surfaced on the Steelers’ final injury report after he was limited in practice Friday for a non-injury reason.
Roethlisberger and Bruce Gradkowski are the Steelers' only active quarterbacks for their 1 p.m. ET game at Heinz Field.
Roethlisberger will try to improve to 17-2 lifetime against NFL teams at Heinz Field, and he needs 117 passing yards to reach 35,000 for his career.
The Steelers are without a handful of starters Sunday because of injuries.
Left guard Ramon Foster will miss his second consecutive game because of an ankle injury despite practicing every day last week. Foster was limited in practice Friday, and he will be replaced by Cody Wallace in the starting lineup.
