While it was known that the Stars would be without their top defenseman through the 4 Nations Face-Off, it appears Miro Heiskanen will be out even longer than that. Lia Assimakopoulos of the Dallas Morning News relays that the blueliner is expected to require surgery with the recovery time being unknown at this time. However, head coach Peter DeBoer expressed optimism that Heiskanen would be able to return before the end of the regular season. The 25-year-old, who was placed on IR today to open up a roster spot, has 25 points in 50 games this season while logging over 25 minutes a night. Now that he’s expected to be out longer term, it wouldn’t be shocking to see Dallas look to add some help on the back end between now and the March 7th trade deadline.
