Brady Quinn in, but not for the reason you expect

Matt Cassel finally came out of the game, but not for the reason you’d expect.

The justifiably maligned Chiefs quarterback was knocked out of the game when he took a hard shot from a pair of Ravens defenders. The Chiefs announced he had a head injury, and his return was questionable.

Brady Quinn immediately jumped up and started warming up, and has entered the game.

The Chiefs trail 9-3, only in the game after four turnovers because the Ravens are playing poorly on offense, and can’t stop a stubborn running game.
