After three Game 7 matchups on Saturday, two more are on tap for Sunday, which is when the opening round of the Stanley Cup playoffs will conclude. By the end of the weekend, the four series will be set for the second round.
It's already known that the Colorado Avalanche will face the St. Louis Blues in one Western Conference second-round matchup. On the other side of the West bracket, either the Calgary Flames or Dallas Stars will advance to face the Edmonton Oilers, who won their Game 7 matchup against the Los Angeles Kings on Saturday.
In the Eastern Conference, the Florida Panthers will be playing the Tampa Bay Lightning.
