The NHL instituted three rule changes today, with the Board of Governors approving these -
1 - Minor Penalty for Failed Offside Challenge
The National Hockey League’s Board of Governors today approved a change to the Coach’s Challenge Rule (Rule 78.7), which will provide for the assessment of a two-minute minor penalty for unsuccessful Coach’s Challenges to alleged Off-Side infractions leading to goals.
The penalty for the unsuccessful off-side challenge replaces the loss of a team’s time-out – which had been in place since the implementation of the Coach’s Challenge in 2015. Under the revised rule, a team does not have to possess its time-out in order to issue a challenge on the particular play – nor will it forfeit its time-out in the event of an unsuccessful challenge.
