In what might have been a playoff series preview Friday night, Nashville forwards Colton Sissons and Filip Forsberg each scored twice to lead the Western Conference-leading Predators to a 4-2 victory over the Avalanche at the Pepsi Center. The rare loss at home put an end to Colorado’s nine-game points streak (6-0-3), and extended the Preds’ winning streak over the Avs to 10, including six straight in Denver.
