Leo Komarov was one of the hardest-working players to ever wear an NHL jersey. He quietly went about his job doing almost anything he was asked in a career that spanned almost a decade with the Toronto Maple Leafs and the New York Islanders and while he went back to Europe to continue his career, he certainly hasn't been quiet.
During a game where he's suited up for Lulea HF of the SHL(Swedish Hockey League), Komarov is clearly seen shoving an official and while it looks like the linesman is possibly embellishing the push or just trying to maintain his balance, it is an obvious no-no for a player to make contact with an official under any circumstances.
