Thompson missed most of the 2020 season with a shoulder issue, which required surgery in mid-January. He had six goals and six assists (12 points) in 16 games with Rochester (AHL) and only appeared in one game with the Sabres. Since being selected No.26 overall in 2016, Thompson has just 10 goals and 11 assists (21 points) in 107 career NHL games.

Bishop only played in the first Stars' round-robin game and then missed the third due to being "unfit to play." However, head coach Rick Bowness said he's available to start Game 1 vs. Calgary and likely will. He allowed four goals on 32 shots in the round-robin loss to Vegas and was 1-1-1 with a 2.29 GAA and .916 SV% in three games vs. the Flames this season.

Ennis was hurt in the second period of Game 2 after being hit into the end boards by Kirby Dach. Ennis was in visible pain and had to be aided off of the ice. With Ennis out, Andreas Athanasiou stepped into a larger role. It remains to be seen if that will be the case again in Game 4.
