From a few days ago (I'm guessing this must be a concussion):

Defenseman Oliver Ekman-Larsson, who has missed the past several games because of an upper-body injury, will accompany his teammates on the hectic trip. Ekman-Larsson ranks fourth on the team and seventh in the AHL among defensemen with nine points.

“We’re not sure if he’ll get into a game or not,” Edwards said. “We’re going to be overly cautious with him and see how it goes day to day. He skated with the group for the first time (on Wednesday) and he’ll have a full practice with the group (on Thursday). We’ll just see how it goes this weekend.”
