Acciari is expected to miss the next two games but shoulder return in Nashville next week. With Acciari and Carter Verhaeghe both on the path to return in the next two weeks, the Panthers are going to have to make some very difficult lineup decisions.

Grzelcyk has missed the last five games with an upper-body injury but will play Tuesday in Buffalo. Grzelcyk will be back on the top pair and top power-play unit. He's had a tough year with injuries but has been effective when healthy, scoring three goals with 10 assists (13 points) in 25 games.

Acciari will miss his second straight game with an upper-body injury. With Acciari out, Sam Bennett made his Panthers' debut over the weekend and Lucas Wallmark centres the fourth line.

Penguins' GM Ron Hextall is familiar with Carter, having been a part of the management in Philadelphia and Los Angeles, where Carter has played his entire career to this point. Moving Carter opened up some cap space for the Kings to sign Alex Iafallo and provides plenty of middle-6 flexibility for the Penguins. Carter, who played most of his career at centre, has played primarily on the wing in 2021. He could centre the third line or move up and play on the right-wing with Evgeni Malkin. He had eight goals and 11 assists (19 points) in 40 games this season.

Grzelcyk was forced to leave Saturday's game with an upper-body injury and did not return. With Grzelcyk out, Jarred Tinordi will draw back into the lineup and Steven Kampfer will likely see some PP1 time.
