British Greco-Roman wrestler Myroslav Dykun has been suspended after testing positive for amphetamines, British Wrestling have confirmed. The 29-year-old, originally from Ukraine, failed a test for the drug and is awaiting the outcome of a B sample.
"I can confirm that he has failed his A sample. The drug was amphetamines," British Wrestling's chief executive Colin Nicholson said.
Dykun won gold in the 2010 Commonwealth Games in the 66kg category and is seen as one of Britain's best hopes of a medal at this summer's Olympics.
He will now miss the Games if his B-test returns positive, and has already been banned from competing and had his funding stopped.
