Jockey Gavin Sheehan was replaced by Davy Russell for the opening race at Aintree on Friday afternoon following a failed breath test for alcohol.
The Grade 3 20 Years Together, Alder Hey & Aintree Handicap Hurdle was won by Dan & Harry Skelton with Langer Dan, with Russell in the saddle on Speech Bubble.
He finished eleventh, following the late call-up which was brought about when the BHA removed 29-year-old Sheehan from duty after detecting levels of alcohol above the threshold.
