The Oakland Raiders’ interest in cornerbacks continues.

According to an NFL source, the Raiders, who are in need of two starting cornerbacks, are showing interest in Denver cornerback Tracy Porter. Oakland has also shown interest in cornerbacks Terence Newman and Mike Jenkins. Newman is expected to choose between Cincinnati and Oakland soon.

Porter is also getting interest from his original team, New Orleans. He could be a backup plan there should Nnamdi Asomugha not sign with the Saints.

Oakland’s interest in Porter is not surprising, as coach Dennis Allen was his position coach in New Orleans. Porter signed a one-year deal with Denver last year. He started the season as a starter but he fell out of favor with the team after he dealt with the affects of a seizure suffered in the summer. He never regained playing time once he was healthy.
