The Pittsburgh Steelers' 18-16 wild-card win over Cincinnati on Saturday night came at a heavy cost.

The right shoulder of quarterback Ben Roethlisberger is aching and wide receiver Antonio Brown is dealing with a concussion after absorbing a hit to the head from Bengals linebacker Vontaze Burfict that set off a bizarre chain of events that ended with Chris Boswell's winning field goal with 14 seconds left.

The availability of the cornerstones of the NFL's third-ranked offense for Sunday's game with the Denver Broncos is unclear.

Roethlisberger will be evaluated this week and Brown's teammates insisted the All-Pro was "fine" after appearing to be briefly knocked out after getting drilled by Burfict.

Roethlisberger had to be carted to the locker room late in the game because of a right shoulder injury (the result of another Burfict hit) but came back to direct the final scoring drive. It was clear, though, that his throwing arm was hurting.
