Early in the second period, Panthers defenseman Dmitry Kulikov hit William Nylander into the boards behind the Panthers net. The play looked scary as Nylander was already stumbling and he landed head-first going into the boards. There was no call on the play.
Luckily, the Swedish superstar appeared to be just fine after the play as he quickly picked himself back up and got back into the play. Regardless though, hits like this should draw calls every time as players can and will get hurt.
