The Dallas Stars are facing the Colorado Avalanche in a crucial Game 5 of their playoff series, but Miro Heiskanen remains sidelined. Despite traveling with the team and participating in morning skates, he has yet to recover sufficiently from his knee surgery to return to the lineup. Coach Pete DeBoer confirmed that Heiskanen is not ready to play, while Oskar Bäck will rejoin the roster, taking the place of Mavrik Bourque, who substituted for Bäck in Game 4 after an oblique injury.
