A hearing is scheduled for Thursday.

"The effect of the recent ambush marketing deals signed by Jerry Jones," said Roger Headrick, chairman of NFL Properties, "has been to undermine existing NFL Properties sponsorships and contracts that were made on behalf of all 30 clubs and to inhibit NFL Properties' future arrangements. Our sponsors and licensees keep asking us whether we are representing all 30 N.F.L. clubs, or just 29 in competition with the Cowboys."

Jones was not available for comment.

In signing the Nike and Pepsi deals, Jones has said he was not trying to wreck the revenue-sharing scheme that binds National Football League owners. Rather, he said he was operating legally by conferring stadium, not team, rights on Nike and Pepsi. The Nike swoosh logo is now painted on Texas Stadium and a Nike-Cowboys theme park at the Irving, Tex., facility is in the planning stages.

Nike is also outfitting Cowboy sideline personnel (anyone not wearing a jersey), but the swoosh is not visible. Only Starter, Champion, Reebok, Logo Athletic and Wilson are authorized N.F.L. sideline apparel makers. Nike has sought a license for years.

Recently, Jones said: "I am well advised and sensitive to playing by the rules. There is no way that I'm in violation of any N.F.L. rules."

But the league evidently feels otherwise, asking the court to "order the defendants to stop violating their agreements with NFL Properties."
