The Panthers announced the news early in the second period of their game on Tuesday night. It's unclear when Barkov was hurt or the severity of the injury. He did have an assist on Sean Bergenheim's goal late in the first period that tied the game at 2.
Barkov was selected with the No. 2 pick in the draft last summer. He entered the game with a team-leading 23 points (eight goals, 15 assists), which ranked ninth among NHL rookies.
Earlier this month, the 18-year-old was selected to play for Finland at the Winter Games in Sochi.
I'm just excited about the opportunity. I've been on the ice earlier than usual and in the weight room, pushing around a little more weights than usual. Every day I go into a workout with a smile on my face and ready to go. When you do have a little more responsibility, you want to take your lunch pail and get ready to work.
