Raiders add returner Walter Powell from Bills practice squad
Powell's agent Brian McLaughlin said on his Twitter account Friday that Powell is joining the Raiders' active roster.
Powell played four games for the New York Jets last year. He returned eight kicks for 233 yards and 12 punts for 48 yards. He was cut before the season and joined Buffalo's practice squad.
Oakland had an empty roster spot after waiving safety Keenan Lambert on Thursday.
