Quinn being evaluated for concussion
Oct 29, 2012 at 1:06p ET
Coach Romeo Crennel said Monday that Quinn will start against the Chargers if he's cleared to play. Otherwise, Matt Cassel will be back under center for the Chiefs.
Quinn was hurt in the first quarter of Sunday's 26-16 loss to the Oakland Raiders, though it's unclear when the injury occurred. He was sacked by Rolando McClain late in the first quarter and then took another shot while floating a pass that was picked by Matt Giordano.
Crennel said that Quinn wasn't at the practice facility Monday while he underwent tests, and Cassel would run the first-team offense during a walk-through practice.
