Kallgren won eight games in his fourteen appearances for the Maple Leafs last season, serving as a backup and fill-in for former Leafs goaltenders Jack Campbell and
Petr Mrazek. As the Leafs acquired goalies
Matt Murray and Ilya Samsonov in the off-season, Kallgren was assigned to the Marlies out of camp.
This definitely wasn't the start to the season the Marlies were hoping for, but hopefully, the injury sustained is not severe and Kallgren will have a speedy recovery.
