Officials at the Jockey Club expect to announce a verdict tomorrow after hearing all the evidence in the Red Lancer inquiry.
Trainer Shaun Keightley and jockey Pat McCabe face a variety of charges over the running and riding of Red Lancer, who finished unplaced at Wolverhampton in October 2003.
The case also involves Christopher Coleman, his son Dean and Neil Yorke, all of whom have already been warned off following previous inquiries.
All the evidence and summaries have been presented to the disciplinary panel and they have called back all those involved for 10.30am.
