The injury to Karlsson (undisclosed) is not considered serious by head coach Guy Boucher, Dean Brown of TSN 1200 reports.

EDGE Analysis

Karlsson is one of the top offensive defensemen in the NHL, so it's a big loss to seasonal fantasy and DFS players. However, it sounds like Karlsson's absence is more of a precaution than anything else, as Boucher tries to preserve one of his biggest assets for what the team hopes is a long run in the postseason.
