"It's safe to prepare as if Landry Jones is our quarterback this week," Tomlin said. "He's healthy."
Jones replaced Vick in the third quarter on Sunday and threw two touchdown passes in a 25-13 win over the Cardinals. Vick revealed on Monday that he has a "tiny tear" in his hamstring. Roethlisberger is probably at least one more week away from a return from a MCL sprain and bone bruise in his knee.
Roethlisberger provided an update on his health during a Tuesday radio spot on KDKA-FM. The quarterback assumes he will split first-team reps with Landry this week.
"It's going to have to be a feel thing, a comfort level," Roethlisberger said. "It's too hard to put a percentage on where I am right now because as I sit here right now talking to you guys in a chair, I feel great, I feel 100 percent. But I don't know anything until I go out and try to do football-related movements on Wednesday."
