Erik Karlsson has not been at a team practice yet during this training camp. The defender is dealing with an undisclosed upper body injury that officially listed him as day-to-day.
Karlsson recently took to the ice a couple times before practices for quick skates. But he was off the ice yesterday on what the team called a scheduled day off, and was again not on the ice for a second day in a row today.
In all practices up until today, the Penguins have been using Sebastian Aho as what looked like a placeholder for Karlsson on a pair with Marcus Pettersson.
