A new rule is set to be tested in The Junior Hockey League's next year that will prohibit players from returning into their zone with the puck during 3 vs 3 overtime.
The Junior Hockey League is the KHL'sjunior affiliate that will test this new rule and it looks like the NHL might look into it as well.
The Junior Hockey League will test new rule in the 2024-25 season:
Players are not allowed to skate with the puck back to their half of the ice in OT. A minor penalty shall be imposed upon the team starting the 2nd violation of the rule.
The NHL already made some interesting changes in recent years with overtime becoming 3 vs 3 which is why this new rule being implemented is definitely a possibility.
