Although Marner was not wearing cut-resistant socks, he did have cut-proof wrist protection. Fortunately, Marchenko is relatively lightweight, and Marner emerged unscathed. Injuries of this nature can lead to severe consequences, so Marner was extremely fortunate.
It is likely that Marner will begin wearing cut-resistant socks after this close call. He was fortunate this time, and hopefully, he can use this experience to fuel an unstoppable performance in the playoffs.
