KANSAS CITY, Mo. - The Chiefs signed their three remaining draft picks on Friday, including first-round selection Marcus Peters, bringing all nine under contract before rookie minicamp.

Along with Peters, a cornerback taken No. 18 overall, the Chiefs signed third-round picks Chris Conley, a wide receiver out of Georgia, and Steven Nelson, a cornerback from Oregon State.

Peters was kicked off the Washington Huskies after run-ins with coaches last year.

The Chiefs also signed Charles Tuaau, a 6-foot-5, 310-pound defence tackle from Texas A&M-Commerce who was not chosen in this year's draft.

Kansas City's three-day rookie minicamp begins Saturday.

To clear roster space, the Chiefs waived tight end Brandon Barden and defensive tackle Hebron Fangupo.
