Bad things happen in hockey sometimes, and it's nobody's fault. That sure looks like what happened in the Stone and Heiskanen incident, says Ken Campbell.

The rivalry between the Vegas Golden Knights and the Dallas Stars has brewed over the years with a new talking point after their final regular season game of this season on Tuesday.

In the third period of a tight contest, Stone was tripped by Stars forward Roope Hintz, causing him to lose balance. As he fell to the ice, he took out Heiskanen’s leg. The blue liner immediately grabbed his left knee and was in visible pain as he headed towards the tunnel with the help of his teammates.
