The Panthers signed fifth-round pick Zack Sanchez Thursday.
An early entry to the 2016 draft, Sanchez was a three-year starter at Oklahoma and one of three cornerbacks the Panthers drafted in the wake of letting All-Pro cornerback Josh Norman leave via free agency.
The Panthers drafted James Bradberry in the second round and Daryl Worley in the third and previously signed both to their rookie contracts.
Sanchez was a first-team All-Big 12 pick and second-team All-American in 2015, when he had seven interceptions.
