A Korean Olympic Committee (KOC) official confirmed Tuesday that Park, a national icon in South Korea, could fall foul of a new rule barring any athlete suspended for doping from competing with the national team for a period of three years.
"Should the rule be applied as it is, Park would be unable to take part in next year's Olympic Games," the official, who declined to be identified, told AFP.
The rule, instituted by the KOC last July, states that the three-year ban on representing South Korea in competition begins on the date the doping suspension expires.
The KOC official stressed the three-year rule had yet to be tested and added that the committee had not taken any position on whether it should be applied to Park.
"There is always room for flexibility," he said.
Park has 21 days to appeal against the FINA suspension with the Court of Arbitration for Sport (CAS), although FINA executive director Cornel Marculescu told AFP he did not expect the swimmer to challenge the decision.
