Norman Williamson has yet to decide who he will ride in Saturday's Victor Chandler Handicap Chase at Ascot.
The jockey has been linked both to the Venetia Williams-trained Nordance Prince and to Direct Route from the Howard Johnson stable.
However, both trainers will wait before confirming their riding arrangements.
Williamson's agent Dave Roberts said today: "There is no decision yet.
"I spoke to Norman earlier today and he said he hadn't made his mind up."
Howard Johnson could use Richard Johnson aboard Direct Route should Williamson be unavailable, his namesake having ridden the gelding in a racecourse gallop at Musselburgh last week.
Johnson was also aboard Nordance Prince when the nine-year-old won the First National Gold Cup at Ascot in November.
