Should the Rangers get anything less than three points in their last six games - and quite possibly all four - out of their weekend games in Tampa Friday and in Sunrise Saturday, they could find a knockout blow waiting for them back in the Northeast.

Henrik Lundqvist was furious once the Rangers’ overtime loss on Saturday in Toronto was in the books, letting his equipment and himself have it and lamenting the “(bleeping) terrible goal” he let in that tied the game in its dying minutes.

Sean Avery was knocked out midway through Saturday’s game when his knee was knocked into the boards as he tried to beat Leafs defenseman Luke Schenn to an icing touch-up. He was walking gingerly but under his own power after the game.

Holding a two-goal lead after 20 minutes, the Rangers surrendered three unanswered goals, including Tomas Kaberle’s equalizer with 3:35 to play and Nikolai Kulemin’s game-winner 39 seconds into overtime for a crushing 3-2 loss to the Toronto Maple Leafs.

A three-game winning streak? That would qualify as a true roll for a Ranger team that has strung three wins together only once in this calendar year. They have a chance to make it twice Saturday night and help keep their outside shot at the playoffs alive when they visit the Maple Leafs in Toronto.

Chris Drury scored a game-tying goal with 16.5 seconds to play to snag one point, and the brilliant Henrik Lundqvist snagged the second in a shootout as the Rangers came from behind all night to beat the Devils, 4-3.

There are still 10 games remaining on the Rangers’ schedule, 20 points up for grabs and two flawed teams above them in the Bruins and Thrashers. The numbers say the Rangers are still in the hunt, and as Henrik Lundqvist said: “As long as we have a chance we’re going to fight.”

Miroslav Satan broke a scoreless tie in the second period, Tuukka Rask made 23 saves and the Boston Bruins handed the Rangers a 2-1 defeat that is a devastating blow to the Blueshirts’ playoff hopes. The Blueshirts remain in 10th place.

It isn’t win-or-go-home Sunday in Beantown, not quite yet, but in some of the Rangers’ minds it may as well be. “It better be,” Brandon Dubinsky said. “We’ve gotta have it. It’s the most important game of our season.

There is plenty for John Tortorella to iron out and only 12 games left to do it, continuing Thursday at the Garden in the Rangers’ final out-of-conference game of the season, against a St. Louis Blues team whose playoff hopes are all but buried out West.
