The NFL and the NFL Players Association held their longest talks Tuesday, meeting for more than nine hours at the Federal Mediation and Conciliation Service building. During the mediation session, the union held a conference call to announce it has retained an international investment bank to help players interpret any financial numbers they receive from the league. The CBA expires Friday at 11:59 p.m. ET. It originally was scheduled to expire this past Thursday, but that deadline was extended 24 hours. The deadline was pushed back another week after Friday's meeting.
