NFL statement on negotiations with NFL Referees Association:
"Negotiations with the NFL Referees Association on a new collective bargaining agreement remain unresolved and the previous CBA has expired. Therefore, in order to ensure that there is no disruption to NFL games this season we will proceed immediately with the hiring and training of replacement officials.
"Our goal is to maintain the highest quality of officiating for our teams, players, and fans, including proper enforcement of the playing rules and efficient management of our games.
"Another negotiating session took place Sunday under the auspices of the Federal Mediation and Conciliation Service. We appreciate the efforts of the FMCS and will continue to be available to the NFLRA and the FMCS to negotiate a fair resolution. We have great respect for our officials and in keeping with that view have made a proposal that includes substantial increases in compensation for all game officials."
The NFL negotiating team is led by Jeff Pash and Ray Anderson.
The previous agreement was for six years (2006-2011).
Negotiations on a new CBA began last October.
Regional training sessions for replacement officials will begin later this month.
