Richard Quinn has an early appointment at Portman Square tomorrow morning when he goes before the Disciplinary Committee of the Jockey Club.
The Scottish-born jockey has been referred by the Ascot stewards over his use of the whip aboard Shibboleth, fourth in the St James's Palace Stakes last week.
As the race was of Group One status, Quinn's case must be automatically sent to be handled by the Jockey Club.
He also appears later when appealing against the £1,000 fine he received from the Epsom stewards for his failure to parade in the correct order before riding Beat Hollow in the Vodafone Derby.
