The incident occurred during the first period of Friday's game. Connor Clifton was lining up Hischier, who was unaware of the Sabres defenceman being near him,for a hit, when he goes right through the New Jersey captain with his shoulder.
Clifton will miss Sunday's game against the Colorado Avalanche and Wednesday's game against the Philadelphia Flyers. He'll be eligible to return to Buffalo's lineup on Friday, November 3rd against Philadelphia.
