On March 10th, 2014, the NHL saw something it rarely ever sees: a player collapse and enter cardiac arrest in the middle of a game. 33-year old Rich Peverley suffered a cardiac incident during a game against the Columbus Blue Jackets after finishing a shift for the Dallas Stars.
Peverley was revived moments later due to quick action taken by the Stars medical staff. Since then, he has been working to find a way to get back in the game, even with his off-balanced heart. But he was never able to fully resume his role as an offensive forward, which led to him officially announcing his retirement from hockey on Friday.
