Corach Rambler provided Fox and trainer Lucinda Russell with a second victory in the Aintree spectacular last season, with the pair having also successfully combined with One For Arthur in 2017.
Following an excellent effort in defeat when third in the Cheltenham Gold Cup two weeks ago, Corach Rambler is the clear favourite to successfully defend his crown on Merseyside on April 13 – and despite speculation to the contrary, Fox looks set to be in the plate once more.
Reports on Thursday suggested the Sligo-born jockey could be in trouble with the Whip Review Committee following his winning ride aboard the Russell-trained Clovis Boy at Newcastle on Tuesday.
However, while the BHA confirmed the ride was being reviewed, and a penalty may yet therefore follow, any potential suspension will not kick in until the week after the National.
The BHA does not normally comment regarding which riders may or may not have been referred, but has done so on this occasion, stating: “Given the speculation in the media in this instance, and the potential ramifications for the public betting on this race, we felt it would be helpful to clarify the situation.”
A BHA spokesperson said: “The WRC today considered a ride by Mr Fox at Newcastle on Tuesday. Upon reviewing the ride, the WRC had further questions for Mr Fox and have written to him today to seek his observations, as is outlined in the protocols and procedures around WRC meetings.
“As a result, Mr Fox’s case will be considered by the WRC on Tuesday, April 2. Any potential penalty arising from this ride, therefore, will not come into effect until Tuesday, April 16.”
Corach Rambler is currently the 4/1 favourite for National glory.
