The Montreal goaltender kept his team within striking distance a few minutes later, robbing Alex Tuch with a terrific pad stop on a 2-on-1 with former Canadiens captain Max Pacioretty before Corey Perry came close at the other end.

Fleury then made another stop on Tyler Toffoli with five minutes left, but misplayed the puck behind his net and gifted Anderson the tying goal with 1:55 remaining.
