Tampa Bay Lightning defenceman Erik Cernak will have a hearing Tuesday with the NHL's Department of Player Safety for elbowing Buffalo Sabres defenceman Rasmus Dahlin on Monday night.

Dahlin left the game after the hit in the second period, and Sabres head coach Ralph Krueger confirmed that his blueliner had a concussion.

"Very disappointing and we'll let the league deal with the judgment of what happened," Kruger told media after the game. "But again, right now we're just worried about Rasmus and getting him healthy and hoping that it's not a long-term injury."

Cernak did not receive a penalty on the play. Tampa Bay won the game 5-2.

It's not clear how long the first overall pick from the 2018 NHL Draft will be out. Dahlin has a goal and 15 assists in 23 games this season.
