The NHLPA has released a memo announcing the players will be fined $5,000 each for intentionally striking a teammate during a game, but the NHLPA also warned that players may be subject to further discipline if a concussion occurs during a match.
The NHL will also conduct a “consensus review” of concussion protocol to determine how it should be implemented in future.
The memo said the league would consider the recommendations of the consensus review and will issue a statement on the subject shortly.
The league’s medical officers have already recommended players be suspended for one game for any sustained head impact.
It was the first time the league has publicly proposed that players be fined for a sustained head injury.
The decision comes amid growing concern over the increasing incidence of concussions in the NHL.
In November, the NHL announced it would investigate the concussion risk of players.
A new study released last week said there are as many as 12,000 concussions among active players in the league each year, though the number of concussed players is far higher.
The latest concussion-related incident, the latest of many to hit the league in recent months, comes as the NHL is attempting to reform its concussion protocol and improve the health of its players.
The new memo outlines the findings of a four-month review conducted by the league’s independent medical staff.
The team was suspended for the first 10 games of the 2016-17 season after a concussion-injury suffered by center Nicklas Backstrom.
The players’ union filed a grievance against the league after the league announced the player was suspended.
The incident is being investigated by the NHL’s independent review team.
