The NFL issued a release before Commissioner Roger Goodell's press conference Monday acknowledging the Cowboys and Redkins have filed a grievance over losing salary cap money over the next two seasons. Next step: the arbitration will be heard by Professor Stephen Burbank of the University of Pennsylvania. No date has been set for that hearing. The release said the NFL and its clubs will have no further comment at this time, which likely means Goodell will decline to answer all questions about this issue in his press conference and refer to the statement.
