The NFL and NFLPA will hold negotiating sessions Monday and Tuesday in an effort to get a new collective bargaining agreement in place before the beginning of the regular season, per ESPN's Dan Graziano.

“That’s certainly our intent. Our intent is to make sure we have a Collective Bargaining Agreement, we’ve been in it for eight years.
