Because the Steelers play on Thursday this week in Cleveland, head coach Mike Tomlin had his weekly press conference Monday.
As expected, cornerback William Gay could be out of action against the Browns after suffering a concussion from a hit by teammate Ryan Mundy in Sunday's 27-24 loss to Oakland.
Rookie Joe Burnett would start in Gay's place, with fellow rookie Keenan Lewis also likely to get at least some playing time, probably in the nickel in place of Deshea Townsend.
Burnett would slide inside to Townsend's spot, while Burnett would play on the outside.
Tomlin also said wide receiver Hines Ward may miss the game after suffering a hamstring injury while making a catch on the next-to-last play of the game.
Rookie Mike Wallace and second-year pro Limas Sweed would share time at Ward's spot, with veteran Shaun McDonald likely to be re-signed - though Tomlin didn't name him specifically.
Tomlin said veteran quarterback Charlie Batch could return to practice this week, meaning Tyler Palko would no longer be needed and Palko would likely be released to make room for McDonald.
Tomlin said other changes could be made as the team tries to get out of the four-game tailspin it is currently in. And, he said those changes could come in all three phases of the game.
