Michael Kinane was yesterday considering his options regarding a possible appeal against the seven-day ban he picked up at Newmarket on Thursday.
The prized ride on Johannesburg in the Kentucky Derby is on the line but the only words from the jockey yesterday were "no comment".
Top American rider Jerry Bailey remains on standby to take over from Kinane on the pick of the Ballydoyle pair, Johannesburg or Castle Gandolfo.
The Irish rider has until Monday to lodge an appeal against the irresponsible riding charge he picked up on Sahara Desert in the last race on Thursday.
Another option is the legal route whereby Kinane could seek an injuction against the sterwards decison, forcing them to put the dates back.
Aidan O'Brien said he would be talking to Kinane about the situation but the indications are that Kinane's unavailability would not threaten the appearance of the Ballydoyle horses at Churchill Downs on May 4th.
Meanwhile, a final decision will be taken tomorrow on whether racing can take place on the cross country course at the Punchestown Festival next week.
A preliminary inspection found the banks course to be unfit for racing yesterday.
If the track is found to be unfit tomorrow, the Ladies Cup and the La Touche races are likely to be transferred to the ordinary race course.
