The Ukrainian athletics star Maryna Bech-Romantjuk, 29, has been banned, suspected of doping with testosterone.
This is reported by athletics' independent anti-doping body Athletics Integrity Unit.
Bech-Romantjuk is one of Ukraine's biggest sports stars. She has taken World Championship silver in both long jump and triple jump.
But she has not competed since the Olympic Games in Paris last summer when she finished eleventh in the triple jump final.
