CINCINNATI -- Quarterback Andy Dalton had the cast removed from his broken right thumb on Wednesday and even threw a pass for the first time since the injury, albeit left-handed.
"Andy continues to progress well; he's doing just what he's supposed to do," Lewis said. "We're preparing for AJ McCarron to be the starting quarterback. Whether Andy is the backup or where he is, we'll know down the line."
For now, the Bengals trust that McCarron's steady hand and mistake-free play will help them make a run in the postseason.
Despite being thrust into the starting role when Dalton went down making a tackle against the Steelers on Dec. 13, McCarron has managed to pass for 851 yards and six touchdowns.
Since throwing two interceptions in his relief stint against Pittsburgh, McCarron hasn't thrown a pick in any of his three starts.
The Bengals were considered a Super Bowl contender before Dalton and his 3,250 passing yards and 25 touchdown passes went down. Now it's up to McCarron to lead them.
"I can't worry about what I can't control," McCarron said Tuesday. "Andy's like a big brother to me. I wish him nothing but the best and a fast recovery. But my mindset right now is that this is my offense. I have to take it and go win."
