The illegal boarding hit was not called by any of the officials, but fans have pointed out that the replay clearly shows that Kucherov hit Guhle from behind, right in the numbers. The department of player safety has been making an active effort to crack down on illegal hits, meaning that they will most likely decide to suspend Kucherov.
Another video shows that Guhle's mouth was bleeding after Kucherov's hit. Guhle has continuously proved that he can compete against the tough competition in the NHL. He has had a very good season so far, scoring 6 goals in his role as a defenseman. Guhle's future looks bright, this hit should only be a small bump in his career.
