Williams is to appear at a hearing involving the NFL's bounty probe of the Saints on Friday morning, according to a schedule set by Paul Tagliabue. The former NFL commissioner has been appointed to oversee the latest round of player appeals in the matter.
"They're accusing us of things we didn't do," Smith said after Tuesday's practice. "That's part of the things that we wanted all along was to face our accusers."
Smith and Vilma will leave for Washington from Atlanta after Thursday night's game against the Falcons.
Smith, suspended four games, and Vilma, suspended for the season, have been playing while their appeals are pending.
"We both want to be there, but we know we can't make it. We've both got to play football. That's the way it worked out. We will definitely be there Friday," Smith said, adding that he hopes Williams shows up. "He hasn't confirmed whether he would be there or not. We'll see what happens."
Tagliabue has said he expects to make his appeal ruling shortly after concluding hearings on Dec. 4.
