From now on, if an NHL head coach wants an opposing goal disallowed on an offside review, he better be sure he's right.

A new rule will punish teams that unsuccessfully issue an offside challenge by assessing those clubs a two-minute penalty for every failed review, Sportsnet's Elliotte Friedman reports.

The cost of losing a goaltender interference review will remain the same, as teams that unsuccessfully challenge for that infraction will still give up a timeout, according to Friedman.

There is reportedly one additional rule change that will take effect beginning this season, as teams will no longer be allowed to call a timeout immediately after icing the puck.

Offside challenges became the subject of much controversy last season, and that came to a head on what was briefly the opening goal of the Stanley Cup Final, when Nashville Predators defenseman P.K. Subban's marker was disallowed because teammate Filip Forsberg was deemed to be offside entering the Pittsburgh Penguins' zone.

Colin Campbell, the NHL's director of hockey operations, said back in June that the league was considering a two-minute penalty for failed offside reviews.
