Vegas Golden Knights superstar Mark Stone was helped off the ice during the second period of Thursday's clash versus the Los Angeles Kings.
Stone was in visible discomfort after a seemingly innocent play in the Kings' end. He didn't emerge from the dressing room for the final frame, according to The Athletic's Jesse Granger.
Stone is Vegas' most important forward, and one of the league's top wingers. The 29-year-old led the Golden Knights with 61 points in 55 games last season while averaging over 19 minutes per contest.
He registered three assists in the club's season opener Tuesday against Seattle.
