The NHL’s official website has released a report into how the game of hockey is evolving.

The report, released Friday, says the game is undergoing a major change as players, teams and leagues are becoming more aware of the dangers of head injuries.

It notes there has been a decrease in the number of concussions and the concussion rate has gone down.

It says there are more concussions than ever, but they are more rare.

The NHL says it has taken action to help reduce the number and severity of concussions.

It cites research showing there are fewer concussions in hockey today than at any time in the past 30 years.

The league says the concussion problem is being addressed through the NHL’s Vision Zero policy and the establishment of concussion education programs across all levels of the game.

The latest numbers are from this year’s season, which started in January.
