Karlsson (upper body) said that he's good to go for Wednesday's Opening Night matchup against the Rangers, Seth Rorabaugh of Tribune-Review Sports reports.
Karlsson dealt with an upper-body injury throughout training camp, but the team had sustained optimism that he'd be available for Opening Night. The 34-year-old confirmed after the Penguins' morning skate that he'll be able to suit up against the Rangers. During his first season in Pittsburgh last year, Karlsson logged 11 goals and 56 points, including 17 on the power play, while averaging 24:16 of ice time.
