Eller missed Game 3 after suffering a lower-body injury in Game 2. Eller was on the ice for Friday's game-day skate, centring the third line and seeing PP2 time. Both are good signs that he will be available for Game 4 but he is officially listed as a game-time decision again.
Unlike the first two games, Malkin took part in line rushes and power-play work during the morning skate, so it looks like he will play in Game 3 vs. the Islanders. Malkin was on PP1 and centred the second line with Jason Zucker and Kasperi Kapanen on his wings.
Eller left Game 2 with a lower-body injury and did not return. Eller played just 9:38 TOI before retiring to the dressing room. Head coach Peter Laviolette called him day-to-day, so his status for Game 3 is up in the air.
Malkin missed Game 1 and will be a game-time decision for Game 2. Malkin did not take part in line rushes during Monday's practice, so it doesn't appear as if he will play but keep an eye on his status as the Penguins hit the ice for warmups at 7:00 PM ET.
Grzelcyk is one of 16 regulars who will not be in the Bruins lineup on Tuesday. The Bruins will need to recall multiple players from their taxi squad/AHL to fill out their lineup. Jakub Zboril, who was a healthy scratch last night, should draw in to replace Grzelcyk.
Jarry will miss the Penguins' season finale on Saturday due to an upper-body injury. With both Jarry and Casey DeSmith sidelined, Maxime Lagace will make his Penguins debut vs. the Sabres.
