Evgeni Malkin was a late scratch because of an upper-body injury.
He took part in the morning skate and was in his customary position centering the second line. He also was scheduled to play on the top power play, as he had against the Florida Panthers with much success. Malkin looked fine during the skate. I would assume that whatever is bothering him isn't major, but of course, I don't wish to speak for him.
Emil Bemstrom dressed in Malkin's place. Sullivan said after the game that Malkin is being evaluated but offered no more information. He remains with the team and was seen outside of the locker room following the game.
Malkin might not be what he once was, but it's notable how quickly the Penguins become a one-line team when he's not available.
