The good news is that it doesn't sound serious at all and Harding isn't expected to be out of the Wild lineup for long at all.
"Over the next week, Josh will make a minor adjustment to his treatment protocol," Wild General Manager Chuck Fletcher said. "Josh feels great and he looks forward to rejoining our team for our game in Winnipeg on Dec. 27."
Harding has been the best story in the sport this season, earning starts while Niklas Backstrom was injured and then taking the starting job and running with it. His .939 save percentage is second in the NHL while his 1.51 goals against average is tops. He's a front-runner for the Vezina Trophy as the mid-season mark approaches.
Making it all the more impressive is the fact that before last season Harding was diagnosed with multiple sclerosis. He missed much of last season dealing with it but it hasn't been a deterrent to his game at all since returning until this "minor adjustment" to his treatment.
With Harding going on IR, the Wild recalled goalie Johan Gustafsson to help fill the void for the next few days but let's be honest: it's tough to replace the type of goaltending that Harding has given the Wild this season.
