UNIONDALE, N.Y. (AP) -- The New York Islanders can blame a little-known rule for turning an overtime win into a tie.

The rule (93.b) allows the video goal judge to rule if the puck entered the net prior to the goal frame being dislodged, and the ruling was that Jorgen Jonsson's apparent goal entered the net while the right post was up off its mooring. The Islanders settled for a 2-2 tie with the Vancouver Canucks on Saturday night.

Referee Blaine Angus immediately waved off the goal, which came at 1:50 of the extra session, and video replay supported the call.

"The net has to be completely flat for the goal to count," Angus said. "The (goalie's) left post was raised three or four inches. We don't know exactly when it became dislodged."

Vancouver goalie Kevin Weekes was elated when he saw Angus signal for a review.

"I only knew when they went under review that it wouldn't count," Weekes said. "I had no idea that it was off beforehand. Everything was happening too fast."

Nobody in the crowd of 8,412 knew what happened, because when the decision was made, the only announcement was that the goal was disallowed. No explanation was given.

The tie was the first overtime game for New York this season, while the Canucks have been involved in four extra sessions, with a win, a regulation tie and two overtime ties.

"Most ties on the road are good ties," Vancouver forward Todd Bertuzzi said. "Anything you can muster on the road is huge."

Vancouver took a 1-0 lead 3:03 into the game on Steve Kariya's high backhand from in tight over goalie Felix Potvin's left shoulder. Brad Isbister tied the game on a power-play slap shot from the slot at 5:54, but Brad May put the Canucks back up at 16:28 when he stuffed the puck past Potvin.

Isbister tied the game again at 3:35 of the second period when he fired a sharp angle shot that went off Weekes' backside and bounced in.

"I can say this for myself, and probably for (Vancouver coach) Marc Crawford, but I liked what I saw offensively, but didn't particularly like what I saw defensively," Islanders coach Butch Goring said. "It wasn't a textbook game."

New York defenseman Jamie Heward received a concussion at 8:45 of the third period. He skated over the red line, dumped the puck into Vancouver's zone and headed off for a change, but Canucks forward Donald Brashear hit him from behind and Heward landed face first into the boards. Brashear was tossed from the game.

"I was in another world at that point and didn't feel like moving," Heward said afterwards. "The last thing I know, I was dumping the puck in at the end of a shift. The next thing I know, I was down."

Goring didn't see the play well since it happened by Vancouver's bench, but said he's alarmed at the growing lack of respect players show for each other.

"There's been a lot of talk throughout the league for players having a lack of respect for each other and it's mind-boggling because it's your career out there," Goring said. "I'm glad I'm not playing today, because I'd probably have a very short career."
