ALAMEDA -- Two of the three Raidersplayers who were concussed in Sunday's loss to Cleveland were practicing with the team Tuesday morning, in anticipation of Thursday night's game against Denver.
Safeties Matt Giordano and Mike Mitchell were both on the field during the media access window, while cornerback/punt returner Phillip Adams was an observer.
Also, Richard Seymour, who has missed the last four games with hamstring and knee issues, was nowhere to be seen.
Defensive end Jack Crawford, though, was practicing after missing the Browns loss with a toe injury.
Running backs Darren McFadden and Mike Goodson, both of whom missed the last four games with high ankle sprains, were practicing again, as was newly signed fullback/running back Jamize Olawake.
Offensive coordinator Greg Knapp was running practice in the absence of Dennis Allen, who is back in Texas with the passing of his father Grady.
