Tracy Porter will be staying in the AFC West but leaving Denver.

The Raiders have reached an agreement on a one-year deal with Porter, Adam Schefter of ESPN reports.

Although Porter opened the 2012 season as a starting cornerback in Denver, he began having health problems in October that were apparently linked to a seizure he suffered in the preseason, and he missed most of the rest of the year. Porter thought he was capable of playing and expressed some displeasure at being sidelined, but when he finally returned to the field in December he suffered a concussion in his first game back and didn’t play for the Broncos again.

When the Broncos added veteran cornerback Dominique Rodgers-Cromartie it became clear that Porter wouldn’t be back. Now the 26-year-old Porter will go to Oakland, and if he’s healthy, he’s a solid addition to the Raiders’ secondary.
