The Oakland Raiders signed Jeff George to a contract Monday, bringing back a player who hasn't thrown an NFL pass in five seasons. George, the No. 1 overall pick by Indianapolis in 1990, joined the team in time for Monday's afternoon practice. He previously played for the Raiders in 1997-98, starting 23 games and throwing 33 touchdowns and 14 interceptions. It is not immediately clear what his role will be on the Raiders, who already have Aaron Brooks, Andrew Walter and Marques Tuiasosopo on the roster.
