Former NFL Commissioner Paul Tagliabue and lawyers for the league and the players' union have wrapped up a hearing in the Saints bounties case.
Tagliabue is overseeing the latest round of player appeals in Washington.
Former Saints assistant Mike Cerullo, a key witness in the NFL's investigation, was scheduled to speak Thursday. Former New Orleans defensive coordinator Gregg Williams is to participate in Friday's session.
Two Saints players who were suspended, linebacker Jonathan Vilma and defensive end Will Smith, have said they plan to attend when Williams is there.
Vilma's lawyer attended Thursday's day-long hearing at an office building. Tagliabue and lawyers who attended Thursday declined comment when they left.
