Kieren Fallon could stage his long-awaited comeback from a drugs ban at Tipperary on Thursday, but before that he is scheduled for an appearance at the Old Bailey in London today as he tries to get corruption charges against him thrown out.

Fallon has been banned from riding in Britain since last July owing to a City of London police investigation, the biggest into corruption in British racing.

The Co Clare-born jockey is one of 11 people due to stand trial at the Old Bailey in September.

However, if today's hearing is successful for Fallon, he may be in line for a return at British racing's most high-profile festival at Royal Ascot later in the month.

That ban has not been reciprocated in Ireland by the Turf Club, so Fallon is able to return to riding here when his six-month suspension for testing positive for cocaine in France last year ends tomorrow.

Fallon remains the number one jockey to John Magnier's Coolmore Stud and will be expected to team up with a number of Aidan O'Brien-trained horses on Thursday.

Meanwhile, Frankie Dettori came back down to earth after his high-profile weekend at Windsor last night, with his arrival at the Thameside track creating huge media interest.

Perhaps inevitably, Dettori was quickly back among the winners courtesy of the heavily-backed newcomer Moon Quest (even-money favourite) for Godolphin in the Scott Wilson Maiden Stakes.

He said: "It is not a Derby, but they all count. This was an egg and spoon race, but the horse has won well. The last couple of days have been a complete rollercoaster of emotions and so much has happened.

He then took the course announcer's microphone and exclaimed: "I love you all!"
