— The Washington Redskins are asking a judge to dismiss a former NFL player's lawsuit that accuses the team and former assistant coach Gregg Williams of running a bounty program that encouraged players to intentionally injure opponents. The former player, linebacker Barrett Green, says he was targeted by the Redskins during a game on Dec. 5, 2004, resulting in a career-ending knee injury. The Redskins call Green's case "utterly baseless."
