Karlsson was labeled day-to-day with an upper-body injury on the first day of Penguins' training camp Wednesday, Michelle Crechiolo of the Penguins' official site reports.

EDGE Analysis

Karlsson was no doubt hoping for a bounce-back year after managing just 56 points last season, well off his Norris Trophy pace the year prior in which he racked up 101 points. The addition of coach David Quinn is expected to unlock Karlsson's potential, though that's far from guaranteed. In regard to his injury, the fact that the team classified it as day-to-day should be an indication that Karlsson will be ready for Opening Night against the Rangers on Oct. 9 even if he does miss some preseason action.
