While NFL teams are prohibited from having communication of any kind with players during the lockout, that hasn’t stopped some teams from finding a way to communicate with them.

At least one AFC team was “very aggressively” sending playbooks to its players recently, a source with knowledge of the situation told FOXSports.com.

There was a short period of time back in late April when the lockout was temporarily suspended. And during that time, teams were permitted to have contact with players and many teams used that time frame to distribute playbooks, but it's not certain how many teams took advantage of the opportunity.

Another report from last month stated that coaches and players, despite the rules against it, were using different forms of technology to communicate with each other during the ongoing labor uncertainty.
