The Raiders have signed former United Football League punter Danny Baugher to their practice squad as insurance if Shane Lechler is unable to play this week. Lechler strained his hamstring during last Sunday's victory over the Broncos and briefly left the game. Baugher, who has never played in an NFL game, spent this season with Las Vegas of the UFL. He led the league with a 44.6-yard gross average and 36.7 net.
