American Varvara Lepchenko has been provisionally suspended for an anti-doping rule violation after the 35-year-old returned a positive test for a prohibited substance, the International Tennis Federation (ITF) said on Thursday.
Lepchenko provided a urine sample on July 12 during the Hungarian Grand Prix, which was found to contain metabolites of adrafinil and/or modafinil—both substances prohibited by the World Anti-Doping Agency, the ITF added.
