TEMPE, Ariz. (AP) The Arizona Cardinals have signed first-round draft pick Robert Nkemdiche to a four-year contract with a fifth-year team option.

The $8.6 million contract includes a $4.4 million signing bonus.

Nkemdiche, a defensive tackle from Mississippi, was considered one of the top talents in the draft but slid to the Cardinals largely because of character concerns.

The Cardinals also signed their two fifth-round picks - safety Marqui Christian of Midwestern State and guard Cole Toner of Harvard - to four-year contracts.

The signings came on Friday, the first day of Arizona's rookie minicamp.
