After the game, head coach Sheldon Keefe said that Liljegren suffered a head injury but that there were positive signs for him during and after the game. He also said the defenceman would be re-assessed before Friday's practice.
Liljegren suffered the injury in the first period as he fell while attempting to make a play with the puck. As he went down to the ice, his head collided with the knee of Ducks forward Trevor Zegras.
The 22-year-old skated to the bench but then went to the locker room and did not return for the second period. Liljegren was also assessed a tripping penalty on the play after knocking down Zegras.
In 23 games this season, Liljegren has a goal and five points while averaging 16:16 of ice time.
