Johnsson, 24, was taken into the boards by Coyotes defenceman Niklas Hjalmarsson as he was pursuing the puck in the corner. Johnsson left the game after the hit and did not return. William Nylander has taken his spot on a line with Auston Matthews and Connor Brown.
In 42 games this season, his first full NHL campaign, Johnsson has 10 goals, 12 assists and 22 points. This isn’t the Swedish forward’s first concussion. Back in 2016, he was forced to miss time after taking a hit to the head while playing in a playoff game for the AHL’s Toronto Marlies.
