"Negotiations toward a labor deal that would end the N.F.L. lockout were confronted with a new hurdle Monday when the group of retired players involved in the antitrust lawsuit against the league — angered because they say their interests and representatives are being shut out by both sides in the talks — filed a separate complaint against players and owners.

The class-action complaint was filed in Federal District Court in Minneapolis against the teams, the league, the players named in the Brady v. N.F.L. lawsuit and DeMaurice Smith, the head of the N.F.L. Players Association. It asserted that the sides were violating antitrust laws by negotiating settlement terms that improperly encompassed the rights of retired players in the time since the N.F.L.P.A. renounced its union status.
