This weekend over Friday and Sunday games, the Pittsburgh Penguins had two of their more notable lineups for games. They broke the mold of their typical predictability by calling up and playing Valterri Puustinen from the AHL without so much as an NHL practice. And then sent him down just as quickly the next day. Radim Zohorna appeared in his first NHL game in a month. Brian Dumoulin got sick and recovered. Brock McGinn was injured and will be out for a while. Marcus Pettersson was a healthy scratch for the first time as a Penguin, Dominik Simon was left in the press box all weekend.
