The Fédération Equestre Internationale (FEI) has announced two adverse analytical findings involving prohibited substances.

Samples taken at the CEI1* in Doha, Qatar, on April 22 from the winning horse Centurion, ridden by Abdulla Mubarak Rashed Al Khaili, of the United Arab Emirates, have returned positive for human erythropoietin (EPO, a banned substance under the FEI’s Equine Anti-Doping and Controlled Medication Regulations).

Samples taken at the same event from the second place finisher Sur (Mabrouk), ridden by Mohd Butti Ghemran Al Qubaisi, also of the United Arab Emirates, returned positive for human EPO, as well.
