When will the regular NFL referees return?

Pro football, now in its third regular-season weekend, continues to rely on college referees and apparently will do so for the foreseeable future. Fans, coaches and players are complaining about the replacement refs, but NFL officials indicated late last week that the league and the NFL Referees Association are still far from a deal. The league locked the refs out in June after their contract expired and talks failed to produce a new one.
