Lausanne, Switzerland (SportsNetwork.com) - Korean swimmer Park Tae-Hwan, who won a gold medal at the Beijing Olympics, was given an 18-month ban by the sport's governing body after testing positive for testosterone.
FINA said Monday that the four-time Olympic medalist tested positive during an out-of-competition test.
His ban is retroactive to Sept. 3, 2014, and will run through March 2, 2016, about five months before the start of the 2016 Rio Olympics.
Park, 25, won the 400-meter freestyle and placed second in the 200 at the 2008 Olympics. He earned silver in both events four years later in London.
