The Raiders have reached agreement on a one-year contract with free agent cornerback Tracy Porter, ESPN reported Tuesday.
Porter, 26, played for the Denver Broncos in 2012 and 2013 after playing three seasons for the New Orleans Saints.
Best known for his 74-yard interception return for a touchdown against Peyton Manning in Super Bowl XLIV, Porter was a second-round draft pick out of Indiana. Raiders coach Dennis Allen was Porter's secondary coach with the Saints.
Porter fell out of the Broncos' rotation after issues with medication and regulating seizures limited his availability in October and November.
The first cornerback from outside the organization to sign with the Raiders during free agency, Porter joins Phillip Adams, Chimdi Chekwa and Brandian Ross on the roster.
