The Raiders opened a roster spot Thursday with the release of safety Keenan Lambert. Since we know Reggie McKenzie likes to gets things done on Friday, of course the news has come down of the team adding someone today. That player is wide receiver and return specialist, Walter Powell, who has been signed off the Bills' practice squad as first reported by ESPN's Field Yates.
UPDATE: This signing has been made official along with the signing of recently released safety Keenan Lambert to the team's practice squad.
As a rookie in 2014, he spent four games in New York, returning 8 kickoffs for 233 yards and 12 punts for 48 yards. This preseason he returned a punt 54 yards for a touchdown, but was still among the Jets' cuts prior to the season and was placed back on the practice squad. The Bills signed him to their practice squad on October 6.
Two weeks ago, the Raiders lost defensive back TJ Carrie in a game when he was injured on a punt return. They had already lost Taiwan Jones to an injury and so were down to using Roy Helu Jr and Amari Cooper on kick and punt returns.
Carrie and Cooper are far too valuable as starters on defense and offense to risk losing them on special teams. Therefore Powell's arrival is quite welcome.
