The U.S. Anti-Doping Agency did not send a letter to Ukrainian sprinter Zhanna Pintusevich-Block notifying her of possible drug violations Monday, according to an Olympic source.
Block has been a subject of the agency's nearly year-long investigation into drug use among track and field athletes, according to a source, but USADA did not inform her of potential charges as The Post reported incorrectly Wednesday.
It is unclear whether Block will face charges at any time. Block's husband, agent Mark Block, did not return a call seeking comment.
Letters were sent by overnight mail Monday to 100-meter world record holder Tim Montgomery, sprinter Chryste Gaines and 400-meter runners Alvin Harrison and Michelle Collins.
USADA also sent a different letter to star sprinter Marion Jones, informing her that it had further questions for her. Jones met with USADA for several hours two weeks ago.
The athletes have 10 days to respond in writing to USADA's anti-doping review board, which will then make recommendations about whether the organization should pursue formal charges.
Pintusevich-Block had the distinction of ending Jones's 54-sprint winning streak in 2001, upsetting her to win the 100 world title that year. She resides in Johnson City, Tenn.
