New Jersey Devils forward Marcus Johansson has skated on his own each of the past two days as he recovers from a vicious elbow from Boston Bruins forward Brad Marchand on Jan. 23.

Johansson was diagnosed with a concussion after taking an elbow to the head from Marchand, which landed the Bruins forward a five-game suspension.

The 27-year-old began off-ice work on Jan. 31 but had not taken to the ice until Tuesday. He remains without a timetable for a return after his second concussion of the season.

Marchand initially said he wasn't sure what happened on the play, claiming he collided with Johansson after taking a shot. He later argued he was attempting to avoid contact, a defence that was unsuccessful with the league's department of player safety.

"While we acknowledge Marchand's argument that he is attempting to defend himself from oncoming contact, it is Marchand who initiates the contact on this play," the league noted in Marchand's suspension release. "This is not a defensive maneuver, made for Marchand's protection."

Johansson missed 13 games due to a concussion in November and has missed another 20 games with the latest injury. In 29 games with the Devils this season, Johansson has five goals and 14 points.

He was acquired by the Devils from the Washington Capitals in June for second and third-round picks in the 2018 draft.

Marchand returned to action on Feb. 7 after completing his suspension and has six goals and 16 points in 13 games since.
