The NHL/NHLPA Competition Committee is recommending that coach’s challenges for “goals that may have resulted from goalie interference or offside plays” be adopted as a new rule.
From the Committee’s news release:
The video review process and all decisions on goals where goaltender interference may have occurred will be the responsibility of the Referees at ice level, in consultation with the NHL’s Situation Room in Toronto; similarly, goals that may have resulted from an offside play will be reviewed and determined by the on-ice officials, in consultation with the NHL's Situation Room in Toronto. In order for a coach to make a challenge, the team must have its timeout available.
