Mediator: Differences remain

After seven days of negotiations, the mediator overseeing the NFL's labor negotiations with the NFL Players Union said today that "some progress was made, but very strong differences remain." 

Mediator George Cohen said in a statement today that both sides have agreed to resume mediation next week. The NFL is set to brief its coaches and general managers later today about potential adjustments that might need to be made in the event of a lockout, which would begin next Thursday if a new collective bargaining agreement can't be reached by then.

The NFLPA will also brief player agents about the status of the negotiations on Saturday.
