Andreas Helgstrands (DEN) World silver medalist Blue Hors Matine has failed the initial vet check at the dressage World Cup final in Las Vegas.
The nine-year-old mare was unlevel in trot. Helgstrand can re-present her at 9am today around 6pm GMT but may choose not to.
All the other horses passed their inspection, including the only British representative, Wayne Channons Lorenzo CH.
