According to Russo, Harding's injury is about the worst case in could have been. What is not clear at this point is if his tweet meant either the ACL OR MCL was torn, or if both are torn. This is a big difference in recovery time.
*UPDATE* @MNWild tweets that it is indeed, both the ACL and MCL. Harding out for the season.
For now, Anton "Borat" Khudobin gets the chance to shine as the Wild's new number 2.
