The Kings assigned forward Mike Richards to their American Hockey League team in Manchester, N.H., after he cleared waivers earlier Tuesday. None of the NHL’s other 29 teams claimed Richards, so the Kings held onto his rights. They can recall him in the playoffs, if they believe he can help them. Richards had only five goals and 10 assists in 47 games with the Kings. He last played in the minors in 2004-05, when he played in the AHL playoffs for the Philadelphia Phantoms, the Flyers’ top affiliate. He joined the Kings in a June 23, 2011 trade from the Flyers.
