Warsaw: Poland`s three-time world weightlifting champion Marcin Dolega has been suspended by his federation over suspicions of doping and banned from taking part in next month`s World Championships in Kazakhstan.
The Polish Weightlifting Federation (PZPC) said in a statement that the 32-year-old had been suspended "due to the suspicion of a violation of the rules" until such time as he provides "a complete explanation of the situation".
The PZPC said the International Weightlifting Federation (IWF) had informed Dolega that he provided a slightly high reading for norandrosterone, a metabolite of the anabolic steroid nandrolone, during a tournament in Moscow.
The definitive results will be known in two weeks.
Dolega, world champion at 105kg in 2006, 2009 and 2010, previously failed a doping test in July 2004 as a 22-year-old.
That saw him miss the Olympic Games in Athens later that year.
He has never achieved the same success at the Olympics, with a best finish of fourth in 2008 in Beijing.
