The hearing regarding Mike Tindall's appeal against a £25,000 ban and omission from the England squad will take place at Twickenham tomorrow.
The Gloucester centre announced that he would appeal the Rugby Football Union's charge a fortnight ago.
The 33-year-old was punished by the board after his antics during the World Cup in New Zealand, which included a late-night drinking session in Queenstown during the competition.
Meanwhile, reports carried out by the RFU have been leaked, exposing the full details of England's off-the-field activities during the side's ill-fated World Cup campaign.
