In a post on Facebook, Patrik Kittel says that he will drop out of the Grand Prix competition in Qatar's capital Doha on Saturday.

The reason: the horse Well Done may have accidentally eaten contaminated feed and therefore risks getting caught in a doping test.

"There is a very small risk that it would be visible at a test, but pure sport and the safety of my horses is my highest priority," writes Kittel.

The competition would be part of the Swede's preparations for the Olympics in Tokyo.
