Schaefer pocketed two assists in Saturday's 4-2 loss to the Flames.
The rookie blueliner tried to spark a comeback after the Islanders fell behind 4-0, having a hand in tallies by Jean-Gabriel Pageau in the second period and Anders Lee in the third. Schaefer continues to be the frontrunner for the Calder Trophy, and through eight games in January, he has delivered four goals and seven points.
