Recently, during a game between the Dallas Stars and the Columbus Blue Jackets, Dallas forward Rich Peverley collapsed on the bench. He just fell over only six minutes into the game. Thankfully, every team in the NHL has a protocol for emergency medical situations like this. Their crew sprang into action and rushed him to the hospital. The game stopped for quite a while as everyone waited for news. The entire stadium was quiet.
Here’s an excellent article by Mike Heika about Peverley and hockey players in general that says this far more eloquently than I did.
