Rookie defenseman Robert Bortuzzo, the Penguins 3rd round pick in 2007, is the latest Penguin to suffer a common injury for the team; A concussion. Head coach Dan Bylsma confirmed to reporters after today’s practice that Bortuzzo has a concussion and he is out indefinetely. Bortuzzo joins defensemen Kris Letang, Zbynek Michalek on the shelf with concussions. For tomorrow night’s game vs Islanders, the Penguins might be forced to recall their 5th defensemen from the AHL this season if Deryk Engelland (lower body) is not able to play vs Isles. Engelland though did skate for the second straight day.
