Former world number one Maria Sharapova may never play again following her failed drugs test, the president of the Russian Tennis Federation says.
The Russian, 29, tested positive for meldonium at January’s Australian Open.
When asked if Sharapova would play any more tournaments, Shamil Tarpishchev told R-Sport news agency it was “very doubtful” and added the five-time Grand Slam winner was in a “bad situation”.
In March, Sharapova said she was “determined to play tennis again”.
The International Tennis Federation (ITF) provisionally suspended Sharapova on 12 March.
She is waiting to hear the full extent of her punishment, which could be as much as a four-year ban, although experts say a six-month or 12-month suspension is more likely.
That is because the World Anti-Doping Association (Wada) admitted in April that scientists were unsure how long meldonium stayed in the system.
