This tiger has just been caged. The Bengals were off to a 10-2 start before their two-time Pro Bowler quarterback went down with a hand injury in yesterday’s 33-20 loss to Pittsburgh. Dalton, 28, suffered a fractured thumb that could keep him out until next season. Sources say he’ll be evaluated today with an outside chance of a return for the playoffs. But seeing the league’s top passing QB sidelined dampens Cincinnati fans’ hopes of what was looking like a championship-caliber season.
