Ben Roethlisberger underwent knee surgery on Monday morning though a return date remains uncertain at this time.
Mike Tomlin's statement said that the Steelers are "confident" that Roethlisberger does not have a long-term injury.
Roethlisberger suffered a torn meniscus that will definitely sideline him for Pittsburgh's game in Week 7 against the Patriots.
Roethlisberger said after the game that he "felt something funny in my knee," which prompted a trip to the locker room.
Upon a first evaluation, the team doctor thought Roethlisberger's leg had hyperextended from the contact, said Roethlisberger, who also has bruising in his right knee from a separate, late-game collision.
