It’s horrible luck for the young defender and former first round pick, who faces his third shoulder injury in as many years. De Haan was injured with about a minute to go on Saturday night in the Sound Tigers’ 3-2 win over Wilkes-Barre (video here). Per Mike Fornabaio:

Calvin de Haan reported out for the season with a dislocated left shoulder. #BST
