The Coyotes said Friday that Kuemper is week-to-week after he was injured in the third period of an 8-5 loss to the Wild on Thursday night. Kuemper went into a butterfly position making a save and struggled to get up. He had to be helped from the ice.
Kuemper, 29, played well last season after Antti Raanta was injured and has been superb while sharing the No. 1 goalie job this year.
Kuemper is fourth in the NHL with a 2.17 goals-against average and a 15-8-2 record for the Pacific Division-leading Coyotes.
