Rosen was recently recalled from Colorado (AHL) and will replace Erik Johnson (lower-body) in the lineup on Wednesday. Rosen, who was acquired in the Tyson Barrie/Nazem Kadri trade, has eight points (1G / 7A) in 13 AHL games this season. He had one goal and one assist in eight career NHL games.

Rosen figures to be a part of the Maple Leafs NHL plans in 2018-19 after signing him to a one-way deal. Rosen is an undrafted free agent who came over from Sweden. He has taken his offensive game to a new-level this year, picking up 19 points (2G / 17A) in 24 games with the Marlies.

With Nikita Zaitsev battling an illness, Rosen has been summoned from the AHL, where he has picked up 17 points (1G / 16A) in 50 games. He had one assist in four games with the Maple Leafs earlier this season.

On Sunday afternoon, the Maple Leafs signed Roman Polak to a one-year deal, so Rosen has been sent to the Marlies to create room for the rugged blueliner. Rosen had one assist in his first four games with the Maple Leafs and will make his Marlies debut this week.

Rosen nearly made the Maple Leafs roster and after Martin Marincin cleared waivers he switched spots with Rosen. The 23-year-old will make his NHL debut on Saturday and comes to the Leafs after posting 19 points (6G / 13A) in 41 games with Vaxjo HC in Sweden.
