Four former players sued the NFL on Monday in hopes of joining current players in their antitrust fight against the league. Hall of Fame defensive end Carl Eller, three-time All-Pro running back Priest Holmes and ex-players Obafemi Ayanbadejo and Ryan Collins are listed as plaintiffs in the 44-page complaint filed in federal court in Minneapolis. The retirees want the NFL lockout lifted to ensure their pensions and health benefits remain funded. According to the lawsuit, those benefits will end if a collective bargaining agreement is not renewed by next March 11 -- a year after the last one expired. Shawn Stuckey, an attorney for the retired players, said he intends to ask the court to combine the retirees' lawsuit with the antitrust suit filed by Tom Brady, Drew Brees, Peyton Manning and others.
