The Wild made the announcement Wednesday night, one day after Harding was superb in a shootout victory over Vancouver. He made 29 saves to beat the Canucks, but GM Chuck Fletcher says Harding needs to "make minor adjustments" to his medication.
Harding will have to miss at least a week while on injured reserve. That means he will be out at least three games.
Fletcher says he expects Harding to return Dec. 27 against Winnipeg. Johan Gustafsson has been recalled from Iowa of the AHL to take Harding's spot.
Harding leads the NHL with a 1.51 goals-against average and .939 save percentage.
