New Jersey dropped its fourth straight Monday night, 3-1, to the ninth-placed Islanders. Meanwhile, across the river, the Rangers polished off the Jets 4-2.
Both results moved the New York squads within two points of seventh place. New Jersey, which hasn't been outside the top-eight all season, could be by the week's end.
The Hurricanes, who fell in Montreal on Monday, are three points back and tied with Washington. The Philadelphia Flyers are four points behind the Isles and Rangers.
The Devils have suddenly played more games than everyone in this cluster except the Islanders. They'll be scoreboard watching tonight as the Islanders will host the Jets in a game that could drop New Jersey into eighth.
Meanwhile, the Caps and Hurricanes will meet Tuesday. The winner, coupled with a Jets loss, will move within two points of first place in the Southeast Division.
The Canes have three games in hand on Winnipeg, and Washington has played two fewer than the Jets.
At the East's top half, Ottawa can creep to within two points of Boston if the Senators can knock off the B's tonight in Boston.
Here are the rest of the games with playoff implications in the East:
Ottawa at Boston, 7
Winnipeg at N.Y. Islanders, 7
Washington at Carolina, 7
