Chiefs cornerback Dunta Robinson won't play Sunday against the Cowboys, according to a report from ESPN.

The report that states that Robinson's cousin was hit by a car and is still unconscious. Robinson has been excused by the team to be with his family.

With Robinson unable to play, the Chiefs will likely use either Ron Parker or Marcus Cooper as their third cornerback. It remains to be seen who plays the nickel spot, given that Brandon Flowers and Sean Smith are the starters out wide.
