Darnell Nurse will miss a critical Game 6 of the Edmonton Oilers’ opening round series against the Los Angeles Kings after he was suspended one game by the NHL.

Nurse, who had a hearing with NHL Player Safety earlier Wednesday, was suspended for head-butting Kings forward Phillip Danault late in the second period of a 5-4 overtime loss in Game 5 of their opening round series in the Stanley Cup Playoffs.

After a stoppage in play, Nurse lunged head first into the face of Danault, who was standing at the edge of  Mike Smith’s crease.
