Leftwich missed all but one game in 2010 due to a knee injury and spent all of 2011 on injured reserve after breaking his arm during a preseason game. Yet the Steelers have kept him around because of his close relationship with Roethlisberger and his arm, which remains one of the strongest in the league. Leftwich actually overthrew speedy wide receiver Mike Wallace on a fly pattern against the Chiefs, a rare feat.
"We have all the confidence in the world in Byron," Wallace said. "He's been in this league a long time, and he's played a lot of games. We just need to work on some things in practice this week with him at quarterback, and I'm sure we'll be ready to go by the time the game comes around."
Roethlisberger will be there in Leftwich's ear offering assistance when necessary, just as Leftwich has done for him through the years.
"He can make every throw on the football field," Roethlisberger said. "He's going to do just as good if not better."
NOTES: DE Brett Keisel (shoulder), LT Max Starks (ankle), S Troy Polamalu (calf), RT Marcus Gilbert (ankle), WR Antonio Brown (ankle) LB Chris Carter (abdomen) and Roethlisberger did not practice on Wednesday ... S Ryan Clark was limited in practice after sustaining a concussion against the Chiefs. Clark will meet with team doctors on Thursday for further evaluation.
