Lightning wing Jonathan Drouin will miss tonight's game against the Bruins, and coach Jon Cooper isn't sure when he'll be back in the lineup.
Drouin left Tuesday's game after taking a hit to the head by Islanders D Calvin De Haan, who received a five-minute major for interference, but no supplemental discipline from the league. Drouin didn't return to the game, but has been feeling much better since. GM Steve Yzerman said Drouin is considered day-to-day. It's unknown whether or not Drouin suffered a concussion.
Cooper said Drouin will be evaluated again tonight by team doctors. Asked if he knows whether it's a short-term or long-term absence, Cooper said he didn't know.
