The 49ers could be without left tackle Joe Staley for Monday night's game against the Steelers. Staley is still recovering from a concussion and hasn't participated in practice this week. "You've got to be concerned about everything against Pittsburgh," 49ers offensive coordinator Greg Roman said. "I'm concerned about everything, (their) rush defense is very good. They've got answers for everything."
