If replacement officials are used this preseason, NFL Commissioner Roger Goodell says it should not adversely affect the game. Speaking to the media at Green Bay Packers camp, the commissioner said fill-in refs have been training with player safety in mind and he doesn't think the players will be more at risk. The regular officials were locked out June 3rd after their labor contract expired and the two sides have been at a stalemate since. The Cardinals and Saints play in the Hall of Fame Game this Sunday in Canton, Ohio.
