Minnesota Hockey's board of directors is expected to vote Sunday whether to drop the tougher penalty structure that added more minutes for the most dangerous illegal hits. The rules were adopted soon after Jack Jablonski of Benilde-St. Margaret's was paralyzed by a check from behind. The Star Tribune reports the recommendation to undo the changes at the youth level stems from concerns the stiffer penalties take players off the ice for too long and hampers their ability to learn.
