Chiefs claimed CB Marcus Cooper off waivers from the 49ers. Cooper was San Francisco's seventh-round pick this past April. He'll slot in as depth behind Brandon Flowers, Dunta Robinson, and Sean Smith at corner.

49ers agreed to terms with No. 252 overall pick CB Marcus Cooper on a four-year contract. The third to last pick of the draft, Cooper is facing long odds of cracking the 49ers' 53-man roster. He should be stashed on the practice squad where he'll be developed as a potential special teamer.
