The Raiders have claimed cornerback Phillip Adams off waivers from the Seattle Seahawks according to ESPN's Adam Schefter.
The third year corner was originally drafted by the San Francisco 49ers in the seventh round of the 2010 draft out of South Carolina. He played one full season for the 49ers before being released prior to the 2011 season. He later signed with the New England Patriots where he played five games before being released. He signed with the Seahawks and played one game with the team last season.
The 5-11, 193 pound corner played four seasons at South Carolina culminating in being named First Team All-Mid-Eastern Athletic Conference after registering 48 tackles and 3 interceptions as a senior.
As a pro, he has appeared in 21 games with no starts and 11 tackles and one interception.
The Raiders had seven cornerbacks in the initial 53 man roster. I would expect this signing plus others would cause a couple of those corners to be cut.
