The Blackhawks have been plagued by injuries as of late and they lost another key defenseman in Tuesday's 5-1 loss to the Vegas Golden Knights.
In the waning minutes of the first period, Calvin de Haan took a hit in the neutral zone from Mark Stone, who was penalized for interference on the play, then fell awkwardly and immediately went to the locker room. The Blackhawks later ruled de Haan out for the remainder of the game with a right shoulder injury, which is the same shoulder he had surgery on in the offseason that sidelined him for four-to-six months.
