The Dallas Stars will have to wait a little longer for the return of their No. 1 defenceman.
Heiskanen has been out of the lineup since January after having knee surgery. The Stars defenceman returned to practice before the start of the playoffs but has been considered day-to-day.
In 50 games before the injury, the Finn racked up five goals and 20 assists.
One change Dallas is making to the lineup is having Oskar Back come in for Mavrik Bourque.
The 25-year-old Back has one assist in three games in the playoffs.
Live coverage of Game 5 between the Stars and Avalanche begins at 9:50 p.m. ET on Sportsnet and Sportsnet+.
