NFL general managers were told on Friday that the Saturday start to re-signing free agents and opening team facilities is on hold until the NFLPA accepts the terms of the proposed labor deal, according to sources. An official NFL announcement of the delay is expected later Friday. The NFL's owners approved the 10-year collective bargaining agreement on Thursday evening, but the players have yet to vote on it. Team general managers were told that they could start some business activities the day after acceptance of the labor agreement, sources said, but it's still uncertain when that will occur.
