BLACKHAWKS LOSE KEITH FOR FOUR TO SIX WEEKS

Chicago Blackhawks defenseman Duncan Keith will be sidelined for four to six weeks after he had right knee surgery Tuesday. Keith, a two-time Norris Trophy winner, has two assists in six games. The team said he had a meniscal tear repaired. The loss of Keith, who won the Conn Smythe Trophy last season as MVP of the playoffs, is a huge blow for the Stanley Cup champs. They play in one of the NHL’s toughest divisions, and every point could make a difference at the end of the season. Keith is likely headed for long-term injured reserve, giving the Blackhawks salary cap relief. Lubomir Visnovsky, a veteran defenseman who was with the team during training camp, could be brought back, or the team could promote a minor league player.
