The Colorado Avalanche will be without top defenseman Erik Johnson for three to eight weeks due to a knee injury. Coach Patrick Roy says the team received the update on Johnson after he had a scope Monday. Roy said Johnson was "disappointed by the situation." Roy also said he has a "lot of confidence in our group" and that it will mean "different responsibilities for some of our defensemen."
