Postseason rosters are going to look a little different if the NHL restarts.
In typical seasons, most available NHL-contracted players from a team's AHL affiliate and even some from juniors, college, or Europe will join their NHL club for its postseason run as Black Aces after their own respective seasons are over. There is no roster limit or salary cap in the postseason, so teams usually carry a large number of players.
For the 2020 playoffs, postseason rosters are expected to be limited to 28 total forwards and defensemen, due to the need to regularly test all players involved and likely accommodate them in hub cities. It is expected that the rosters won't be limited when it comes to the number of goaltenders a team can carry, though.
In addition to Matt Murray and Tristan Jarry on the NHL roster, the Penguins have three NHL-contracted goaltenders in the minor leagues -- Casey DeSmith, Alex D'Orio, and Emil Larmi -- and they plan to carry all three on their expanded roster if the season restarts.
DeSmith remained in Pittsburgh during the shutdown, D'Orio arrived in Pittsburgh ahead of the Penguins opening their practice facility, and Larmi will be flying to Pittsburgh on Friday.
Larmi was originally supposed to fly to Pittsburgh on Wednesday, but wrote on Instagram that he "wasn't allowed to get on the plane because I didn't have all the 67 documents, one dinosaur and a few drops of unicorn blood. I only had 58 documents, wrong dinosaur and just the horn of the unicorn."
