On Friday morning, the hockey world lost New York Islanders legend and Hall of Famer, Mike Bossy. The beloved goal-scorer passed away at the age of 65 after it was announced in October that he had been undergoing treatment for lung cancer.

Within his career, Bossy helped lead the Islanders to four consecutive Stanley Cups, had nine straight 50-goal seasons, and currently sits at the top of the NHL’s leaderboard in regular-season goals per game.

Reaction from across both the hockey and sports world poured in, following the tragic news.
