ALAMEDA - The Raiders made a series of roster moves today.
None of them included adding another wide reevier.
The team waived DE Greg Spires, LB Grant Irons and S Jarrod Cooper, who intends to retire.
The team claimed fullback Luke Lawton off waivers from Philadelphia and signed safety Marviel Underwood.
CB John Bowie (knee), WR Drew Carter (knee) and FB Oren O'Neal (knee) were all placed on injured reserve.
The team is also working out defensive back Nate Lyles. If he were signed, the team would have to cut two players tomorrow.
This is the time of the year when the media is no longer allowed to watch practice, so there will be no more details to report.
The special teams session is open. Darren McFadden was back with Johnnie Lee Higgins fielding punts and kickoffs.
*WR Arman Shields (knee) returned to practice.
*The news about Cooper is surprising. No indication he was considering retiring. The Raiders will miss him on special teams.
The coverage units looked bad without Cooper last year.
*For all those that still hate Randy Moss (and there are a lot of you) that trade really doesn't look good right now considering the Raiders will get nothing from Bowie this year.
*Lawton is well traveled. He was traded to Philadelphia from Indianapolis for a conditional draft pick before being waived by the Eagles.
He's also had stops with the New York Giants, Atlanta Falcons, and the New York Jets.
*Underwood is a former teammate of LB Kirk Morrison at San Diego State and is from San Leandro. He was drafted by Green Bay in 2005 and finished last season with Denver.
Underwood tore two ligaments in his knee in 2006 and missed the season before being released by the Packers last year.
