Commissioner Roger Goodell did not attend the meeting.
Williams was summoned to New York after apologizing for and admitting to overseeing the program the last three seasons with a pool that reached as high as $50,000. Payoffs were made for inflicting game-ending injuries on targeted players.
Williams now is defensive coordinator in St. Louis. He also held that position in Tennessee, Washington and Jacksonville. He was head coach of the Buffalo Bills from 2001 to 2003.
