The Penguins have signed Libor Pivko, acquired from Nashville, to a one year contract.
They have also re-signed Alain Nasreddine, presumably to fill out the Wilkes-Barre roster.
I like Nasreddine, and I liked what I saw from him when he was in Pittsburgh last season briefly (six games), but I can't see him cracking the lineup.
Pivko is expected to battle for a roster spot. See my recent article on the forwards for a little bit more on Libor.
