[KC Chiefs.com] In a sign the Chiefs are concerned about their depth, they signed veteran cornerback Mike Richardson. Richardson played for the Chiefs last season as a reserve and went to camp with them this year.

The Chiefs played without starting cornerback Brandon Flowers in last week’s game against Seattle because of a hamstring injury. They lost his replacement, Jackie Bates, early in the third quarter with a knee injury.

To clear roster room for Richardson, the Chiefs released linebacker Justin Cole.
