Coaches will now be able to challenge goal plays that should've resulted in a stoppage of play. The St. Louis Blues lost a playoff game this season because of a hand pass that should've been whistled dead.
Teams will now be able to issue a coach's challenge at any time, but there will be "consequences" if they're wrong. The consequences of an unsuccessful coach's challenge is a minor penalty for the first unsuccessful challenge and a double minor penalty for the second.
Referees are now required to review any major penalty that is not a fighting major as well as match penalties. The refs will either confirm the call or reduce it to a minor penalty. They can't erase the call. Refs can also do an on-ice review of double minor high sticking penalties.
Players that have their helmet come off must immediately go to the bench or retrieve their helmet.
Following an icing or the beginning of a power play, teams will be able to pick which dot in the offensive zone that the faceoff will take place in.
The league is waiting for the NHLPA to approve the salary cap number for this season.
