But according to a report from Mike Florio, the NFL is considering delaying the start of the free agency period, though at this time there are no plans to do so.
From Pro Football Talk:
Per a league source, the NFL currently is contemplating the possibility of announcing on Sunday a delay in the start of free agency. The league wants to wait until after voting on the CBA closes before making a final decision, in order to prevent further delays to the CBA voting process.
