The NFLPA has filed a collusion claim against the league, only a day after an appeal was denied made by the Cowboys and Redskinsto protest the NFL's punishment for front-loading contracts of players during the 2010 uncapped season.

The claim was filed with the U.S. District Court in Minnesota, which means Judge David Doty -- certainly not a favorite of the NFL -- likely would oversee the claim. "When the rules are broken in a way that hurts the game, we have an obligation to act. We cannot stand by when we now know that the owners conspired to collude," NFLPA executive director DeMaurice Smith said in a statement. Said union president Domonique Foxworth: "Our union recently learned that there was a secret salary cap agreement in an uncapped year. The complaint today is our effort to fulfill our duty to every NFL player. They deserve to know, above all, the facts and the truth about this conspiracy."
