The Labor Day weekend apparently will be free of NFL labor negotiations because the Management Council and Players Association have no plan to meet, although the sides remain polarized.

Jack Donlan, Management Council's executive director, said yesterday, "I don't have the foggiest idea" of when he and union director Gene Upshaw would resume negotiations. Each side has accused the other of failing to negotiate in earnest.

As a result, the biggest action in the league yesterday was the Philadelphia Eagles' selection of Ohio State's Cris Carter in the fourth round of a supplemental draft. Pittsburgh running back Charles Gladman was not drafted and will become a free agent, able to negotiate with any team. The Eagles were surprised to find Carter, a former all-America receiver, available when they made the 91st selection. Every other team in the draft passed on using one of next year's picks before the Eagles took Carter.

"We thought it would be a hell of a gift if we got him in the fourth round," Eagles Coach Buddy Ryan said. "He's got something like 27 touchdown receptions. We could use some of those."

But drafting Carter will cost the Eagles more than a 1988 fourth-round pick. Carter and Gladman were declared ineligible for their senior seasons by their respective schools because they accepted money from agents, a violation of NCAA rules.

Several college coaches and athletic directors expressed dismay that the NFL held a supplemental draft. The University of Pittsburgh, upon hearing Philadelphia had taken Carter, banned Eagles scouts from campus. Pitt Coach Mike Gottfried also said the Eagles will not have access to film of players, and that the ban extended to BLESTO, a scouting service used by several NFL teams, including the Eagles and Steelers.

"I regret having to do this, but I do not believe in this supplemental draft," Gottfried said. "I hope in the future that the dialogue that has begun between the NFL and the NCAA will help solve this problem."

Donlan sounded as if he would have been grateful for any kind of dialogue. The NFLPA offices were closed as of yesterday evening and would not be open until Tuesday, according to one employe.

Donlan said he did not talk to anyone from the union on Friday, and added, "This is all so contrived. It's a sham. They don't want to meet. There are a lot of complex issues. It can be worked out, but you have to get in there and do the grunt work."

Donlan accused NFLPA leaders of "looking for some issue to rally the troops . . . because they aren't getting the support from within that they expected. Five years ago {when the players' strike lasted 57 days}, the players were making $90,000 a year, but now the average is more than $200,000. A lot of the players, in effect, are saying they don't think this is so bad."

Donlan said he thinks the strike could be avoided, but also acknowledged the league is negotiating with two banks for a loan of more than $100 million as insurance against potential strike losses. In 1982, the owners lost an estimated $200 million in revenue from television and gate receipts.

"{Donlan} likes to talk and he likes to discuss but never truly bargain," Upshaw told United Press International. "It seems in this industry that across-the-table bargaining doesn't work. It doesn't work because he's never done it."
