One of Britain's top wrestlers was suspended for doping and will likely miss the London Olympics.

Myroslav Dykun, who won the gold medal in the 146-pound Greco-Roman category at the Commonwealth Games in 2010, tested positive for amphetamines and is awaiting the result of a "B'' sample in two weeks.

"He is immediately suspended from competition and funding," British Wrestling chief executive Colin Nicholson said Thursday.

Dykun will receive at least a two-year ban if his "B'' sample is positive.

"Suffice to say our organization will come down hard on the wrestler, as we will any wrestler who takes drugs," Nicholson said.

The 29-year-old Dykun was born in Ukraine but moved to Britain in 2003 as part of the country's initiative to get Eastern European athletes to help homegrown wrestlers develop into medal prospects.

British Wrestling initially said the imports would not be eligible to compete at the Olympics but that position has changed, angering British-born wrestlers.

Britain hasn't won an Olympic medal in wrestling since 1984. Its squad for the London Games will be announced May 10.

Five of the seven places on British Wrestling's elite squad were recently awarded to foreign-born athletes.

Dykun switched to Greco-Roman wrestling from freestyle, in which he won two British titles. He placed ninth in this year's European Championship and 28th in the 2011 worlds, making him unlikely to medal at the Olympics.

"Under no circumstances do we condone drug taking in any form — whether it be recreational or performance-enhancing," Nicholson said. "This is evidence that we are determined to work in partnership to root out anyone misusing substances."
