The Pittsburgh Steelers have confirmed that Ben Roethlisberger will start against the San Diego Chargers on Sunday.

The two-time Super Bowl-winning quarterback has missed three games with shoulder and rib injuries.

Offensive coordinator Todd Haley said: "He looks like himself for the most part. Now I don't know what he's feeling when he's doing some of those things. But it looks like he's moving around pretty good.

"I think he understands his body better than anybody. He's the one that's got to make the decisions and we'll just try to put him in the best positions to succeed."

Wide receiver Mike Wallace added: "When Ben's in, it's just a whole different level of game planning and things that teams have to do just to compensate for how athletic he is."

Third-string quarterback Charlie Batch has played in the last two games for the Steelers, after regular backup Byron Leftwich also sustained a rib injury.
