Hybrid icing will be used during the 2013-14 season. The rule change was officially approved on Monday just in time for the season openers taking place around the league this week. Though the NHLPA ended up passing the motion, numerous players weren't in favor. According to Darren Pang, the St. Louis Blues voted against hybrid icing by a very large margin.
