Basically it amounts to a potential suspension and/or fine should a player hit another player in the head on purpose. In other words the "Matt Cooke" will no longer be allowed without some sort of suspension.
The timeline for this seems to be a bit fuzzy as you read the article you'll see what I mean. It's stated that the rule would be ready in time for tonights games but that the NHLPA would need to vote on it and that wouldn't happen until Friday. Later in the article it says the NHL unilaterally implemented the new rule and that Daly feels the NHL is well within their rights to do so.
So a rule is in place but who knows when it will take effect.
