coach Mike Tomlin
has promoted Jonathan Dwyer
to start at halfback Sunday in Baltimore.
Tomlin listed Dwyer as the starter on the new depth chart that is out this morning with Isaac Redman
No. 2 and former starter Rashard Mendenhall
While Tomlin's depth charts do not always reflect reality -- Ben Roethlisberger
is listed as the starting quarterback this week, as he was listed last week even though he was out -- this is a significant change for him because Mendenhall has been listed as the starter all season.
All four halfbacks on the active list lost fumbles in Sunday's loss in Cleveland.
Mendenhall started and, with a 7-0 Steelers
lead, he lost the first one on the team's second play on offense, his second carry.
After those first two carries, Mendenhall got only two more carries against the Browns. Tomlin pulled him from the game and continued to pull his other backs after they fumbled.
Dwyer, who fumbled when a defender's helmet hit the ball hard, had nine carries for 19 yards.
Redman had two carries and Chris Rainey five.
Dwyer had consecutive 100-yard games before he missed the Nov. 12 game against Kansas City with a thigh injury.
