KANSAS CITY, Mo. — Kansas City Chiefs quarterback Damon Huard didn't play the final three quarters against the Oakland Raiders today after suffering what the team called mild head trauma.

Huard started in place of Brodie Croyle, who separated his shoulder against New England last week. The 12-year veteran was in for Kansas City's first two series, but didn't return after throwing an interception late in the second quarter.

Huard finished 2-for-4 for 19 yards and was replaced by Tyler Thigpen.
