Dakota Joshua will make his NHL debut on Monday when the Blues meet the Anaheim Ducks at Honda Center (9 p.m. CT, FSMW, 101 ESPN).
Joshua will center the fourth line with Kyle Clifford and Mackenzie MacEachern. That position was previously occupied by Jacob de la Rose, but he won't be in the lineup due to a lower-body injury he sustained in Saturday's 7-6 win against San Jose.
