TORONTO — Sheldon Keefe's team was already weathering the loss of two key blue-line pieces.
The Maple Leafs' patchwork defence corps might have suffered another major setback on a night that ended in more 3-on-3 frustration.
Anthony Beauvillier scored at 1:56 of overtime Monday as the New York Islanders came back from a goal down late in the third period to defeat Toronto 3-2 in a game that saw the home side lose No. 1 defenceman Morgan Rielly to injury.
"We played a good hockey game," Keefe said.
