NEW YORK — The NHL and the players’ association swapped proposals Wednesday in an effort to head off a lockout scheduled to start this weekend.

The NHLPA, led by executive director Donald Fehr, made its presentation in the morning, but that was quickly dismissed by Commissioner Gary Bettman, who said it wasn’t much different than earlier offers.

Bettman then met with Boston Bruins owner Jeremy Jacobs, and Murray Edwards of the Calgary Flames, and a new NHL offer was handed back to the players’ association with a shelf life on it.

“We made clear in presenting the proposal that this proposal was intended to lead to a deal before the weekend,” Bettman said after the nearly three-hour meeting, “and that if in fact a deal was not achievable, what we had proposed would be off the table. We were quite clear on that.”

After not meeting face to face since last Friday, the sides gathered Wednesday at the league office before the NHLPA was to hold player meetings later Wednesday at a New York hotel. The NHL board of governors will convene Thursday with Bettman, while the union holds a second day of discussions with more than 250 players.

This was the first formal session since Aug. 31. No new meetings were immediately scheduled, but both sides expected to talk again no later than Thursday after both sides’ internal meetings were concluded.

Fehr said the union’s new proposal was “consistent” with the last one it submitted. The league responded with their time-sensitive counter, and Fehr, despite the developments, admitted he does not “know whether this will lead to anything.”

“Our proposal was made with the same principles that we have always had in mind and those are that we didn’t see any reason — given the seven years of record revenue growth and enormous concessions the players made the last time — to have an absolute reduction in player salaries,” Fehr said. “They are prepared to have their share fall over time as revenues grow, and that we hope to partner with the large revenue teams in terms of providing whatever assistance to franchises may be called for generally under revenue sharing.”

The NHL again came up from their original offer of 43 percent of hockey-related revenues going to the players. In an earlier proposal before Wednesday, the NHL pushed it up to 46 percent, and Bettman said the new offer was even higher without giving a specific number.

“We actually crafted the proposal after we got theirs,” Bettman said. “We concluded that their proposal wasn’t going to get us anywhere. With time running short, we actually crafted a new proposal that is different than the other proposals because it is much simplified.”

In the expiring CBA, the players were given 57 percent of the total. The definition of hockey-related revenues wasn’t changed from the current deal.

“We’re not asking for a rollback,” Bettman said. “We have said that our proposal — the one that is time-sensitive — would have a phase-in, and while it contemplates the possible reduction in player share, if you use our estimates it would be under 10 percent. If you use the players’ association’s estimate on revenue growth, it would actually be seven percent.

“When you factor all of that in, it seems to me that having a work stoppage and damaging (hockey-related revenue) long term really doesn’t make a whole lot of sense.”

As he has all along, Bettman insisted that the league will not operate the upcoming season under the current economic plan, and cited damage that will result from an impending lockout as the reason why the current offer won’t be viable after this weekend.

“What we would be prepared to do now to make a deal before there is extensive damage is not the same that we will be prepared to do in the event we get to a point where we have suffered the damage,” Bettman said. “We looked at their proposal. It was clear that there wasn’t very much movement at all — if any. A little bit around the edges.

“We said we have to try something different which is why we tried to simplify the approach and focus on the percentage.”

Elsewhere, the union filed an application with Quebec’s labor relations board, along with at least 16 players of the Montreal Canadiens, asking it to declare a lockout illegal in the province. A hearing on the application is scheduled for Friday morning in Montreal.

“The players don’t want to see hockey interrupted,” Fehr said. “We believe under Quebec law, a lockout would not be appropriate and would not be legal, so we are asserting that position. We would like to think that is consistent with the interests of the fans and eventually consistent with the interests of the owners.

“We’ll let the legal proceedings take care of themselves.”

What makes this week unique — in addition to the deadline looming over all of it, of course — is the amount of players who will be on hand. It will indeed be the offseason’s biggest show of force. Pittsburgh captain Sidney Crosby, one of the league’s biggest stars, is one of them. He skated on Tuesday with some of his Penguins teammates in suburban Pittsburgh before traveling to New York.

Industry revenue has grown from $2.1 billion to $3.3 billion annually under the expiring deal. Owners asked players to cut their share of hockey related revenue during a six-year proposal. Players are concerned management hasn’t addressed its problems by re-examining the teams’ revenue-sharing format.

“We’re not in position to make a judgment as to whether this is going to be productive. We have to wait and see,” Fehr said. “Every day is in some sense more important than the last one. The commissioner has indicated that a lockout will begin if no agreement is reached. We take him at his word as we have for the better part of a year. So in that sense it is.

“On the other hand, you can only make a deal when people are ready to make a deal.”

If one isn’t struck by midnight on Saturday night, the start of the regular season will be in immediate jeopardy. The season is scheduled to open on Oct. 11. Players would begin missing paychecks four days later.

An 11-day strike in April 1992 caused 30 games to be postponed, and a 103-day lockout in 1994-95 caused the cancellation of 468 games and delayed the season’s start until Jan. 20. The 2004 lockout started Sept. 16 when training camps were to open, as they are this year, and wasn’t settled until July 13.
