Charlie Coyle is expected to miss three to four weeks with a sprained knee. He sustained the ailment late in the second period of Saturday's game against Anaheim when he was checked by Ducks forward Andrew Cogliano. Coyle won the team's second-line center spot out of training camp, so his loss from the lineup will hurt a Wild team that has started the 2013-14 campaign with a 0-0-2 record.
