With 10:42 remaining in the first quarter, Andy Dalton walks up to Bengals center Trevor Robinson on Indianapolis' 41-yard line. Dalton takes the first down snap and drops back with intense pressure coming from the edges. As Dalton releases the football, he's sandwiched between two pass rushers and his throwing arm collides with a Colts defender and Andrew Whitworth's helmet.
Dalton walked to the sidelines after shaking his hand, and then falls to the turf -- as if he was instructed to as he approached the sidelines to get an injury timeout. After a few moments it appeared that Dalton was talking with teammates with a smile or two. Either way Bruce Gradkowski replaced Dalton in the game and he's most likely done for the game.
The team is officially calling it a bruised arm.
Mike Nugent converted a 37-yard field goal to take a 3-0 lead.
