The Browns will be without Pro Bowl DE Olivier Vernon for a second consecutive game when they face Pittsburgh on Thursday.
Vernon and DB Eric Murray, who has been sidelined since undergoing knee surgery earlier this month, were ruled out for the game. Two others -- TE Ricky Seals-Jones (knee) and T Kendall Lamm (knee) -- were labeled questionable.
Vernon suffered a knee injury late in the action Week 9 against the Broncos. Chad Thomas filled the void for Vernon on Sunday against the Bills, picking up his second sack of the season in by far the most extensive playing time of his career, and appears poised to do so again.
Browns coach Freddie Kitchens said Tuesday that Seals-Jones, who has nine catches for 155 yards and two touchdowns, likely would be a game-time decision. Seals-Jones missed the Bills game after being considered questionable but was a full participant in Wednesday's walk-through after being limited earlier in the week.
Lamm has not played since suffering a knee injury Week 1.
For the Steelers, FB Roosevelt Nix (knee), RB Benny Snell (knee) and WR Ryan Switzer (back) won't play. Former Browns CB Joe Haden was added to the injury report Wednesday with an illness and is considered questionable.
