the only changes that will immediately go into effect are:
There are also two changes that will go into effect as soon as this week. The penalty shot rule was clarified so as to include players who clearly are in a pursuit of a loose puck that would lead to a breakaway and are hauled down will now be awarded a penalty shot. Before, a player had to be in control of the puck.
Also, a clarification of the rule regarding goals scored when the net is slightly off - those goals will now count.
everything else will be recommended to the board of governors in july for official approval and wouldn't go into effect until next year (whenever that is) under the new cba
