The playoff races in each NHL conference were shaken up by a handful of surprising results on Monday night.
The New York Rangers fell to the Pittsburgh Penguins to create more chaos in the Eastern Conference wild-card race.
The New York Islanders earned an overtime win over the Philadelphia Flyers and the Detroit Red Wings picked up a road win over the Tampa Bay Lightning.
Those three results tightened the wild-card race, and it could be even more congested depending on what happens between Pittsburgh and the New Jersey Devils as well as the Washington Capitals and Buffalo Sabres on Tuesday night.
