Erica Watts, 24, am open water swimmer from Indiana who finished second at the last US championships has accepted a two-year suspension for what is said to have been an "inadvertent" violation of anti-doping rules, according to the the US Anti-Doping Agency.
The swimmer, from Carmel, Ind., tested positive for methylphenidate, or Ritalin, at the championship meet on June 2 in Fort Myers, Florida. She had disclosed her use of a prescription medication containing the substance at the time of the test, but she did not have a medical exemption in place before the competition, the agency said.
