Karlsson hasn’t come back to the ice since then, being kept off the ice in the name of the rehab process. Sullivan is optimistic that Karlsson’s ailment won’t be long-lasting, but the team has been starting to take steps to prepare for how they might start the regular season without their star defender.

Pittsburgh Penguins’ defenseman Erik Karlsson remained off the ice on Monday due to an undisclosed injury that has prevented him from participating in any of the team’s practices during its ongoing training camp.

The Pittsburgh Penguins have a rough week ahead. After their sunny victory over the Ottawa Senators Sunday, they’ll play four games in the next five days, but the Penguins’ injury list might be a little longer today.

Pittsburgh Penguins star defenseman Erik Karlsson, the franchise's biggest offseason acquisition from a year ago, has yet to take the ice during training camp due to an upper-body injury with no positive updates in sight.

There is a fairly high degree of intensity in the Pittsburgh Penguins training camp this season. Head coach Mike Sullivan and the Penguins failed to make the playoffs in each of the last two seasons and they have not made it past the first round of the playoffs since the 2017-18 season.
