WASHINGTON (AP) - Right from the start, the NFL said Gregg Williams was in charge of a pay-for-pain bounty system with the New Orleans Saints.

Now the former defensive coordinator - who told the league about others' involvement - is slated to be cross-examined by lawyers for players appealing their suspensions in the case.

Friday's session is part of the latest round of player appeals overseen by former NFL Commissioner Paul Tagliabue. Former Saints assistant coach Mike Cerullo faced questions Thursday, when lawyers for the league and for players spent more than nine hours in a Washington office building.

Saints linebacker Jonathan Vilma and defensive end Will Smith have said they'd be present Friday to hear what Williams has to say.
