Head coach Jared Bednar said Friday that Drouin is dealing with an upper-body injury and will miss "the next few games," Ryan Boulding of NHL.com reports.
Drouin will at least be sidelined for Saturday's game against the Blue Jackets and Monday's game against the Islanders before being re-evaluated. He logged 21:25 of ice time during Wednesday's regular-season opener against the Golden Knights and finished with a minus-1 rating. It's not yet clear who could be called up to fill the void left by Drouin's absence.
