The medical news was good and bad for the Kings on Monday. Or bad and good, depending on your point of view. The bad news came late in the afternoon, with defenseman Matt Greene possibly sidelined for the rest of the lockout-shortened season because of a back injury suffered during the Kings' season-opening 5-2 loss Saturday to the Chicago Blackhawks at Staples Center. The Kings said in a news release only that Greene suffered a "mid-body injury" and would be placed on the injured reserve list. The team recalled defenseman Andrew Bodnarchuk from Manchester (N.H.) of the American Hockey League to take Greene's roster spot. TSN, a Canadian sports network, first reported the precise nature and extent of Greene's injury. The good news came earlier in the day, with center Anze Kopitar announcing he was fit to play after a sprained right knee sidelined him for Saturday's game. He said he would play tonight against the Colorado Avalanche in Denver, the first contest on a three-game trip. After participating in the pregame Stanley Cup banner and ring ceremony on the ice Saturday, Kopitar retreated to the dressing room and peeled off his uniform. He watched on TV from the quiet of the room, and he didn't like what he saw from the offensively-challenged Kings.
