Olympic dressage rider Domien Michiels has been disqualified from the team final at the Paris 2024 Games for failing a drug test, caused by his coming into contact with a prohibited substance when treating his ill dog.

The in-competition test was carried out on 3 August, the day of the grand prix special, which decided the Olympic dressage team medals at Paris 2024, and the sample was positive for dorzolamide.
