Maria Sharapova, who has long been the world's richest female athlete, will be suspended from tennis after she admitted to failing a drug test at the Australian Open in January.
A sombre looking Sharapova, speaking at a press conference in Los Angeles Monday, said she'd been taking the drug, meldonium, since 2006 and didn't realize it was declared a banned substance by the World Anti-Doping Agency (WADA) at the start of 2016.
The International Tennis Federation, about an hour after her admission, then said on its website that the 28-year old would be provisionally banned from March 12 "pending determination of the case." The usual penalty for first-time offenders is two years.
The failed drug test came on January 26 -- after Sharapova lost to Serena Williams in the quarterfinals -- and she was charged with an anti-doping violation on March 2, the governing body additionally said. There was much speculation that Sharapova's Monday briefing with reporters centered on retirement plans following an increasing number of injuries, but the failed test was a bigger bombshell. And it came in the wake of match fixing allegation that rocked tennis in Melbourne.
"A few days ago I received a letter from the (International Tennis Federation) that I failed a drug test at the Australian Open," the five-time grand slam winner said in the press conference that was streamed live on Sharapova's website. "I did fail the test and take full responsibility for it.
"For the past 10 years I have been given a medicine called mildronate by my doctor, my family doctor, and a few days ago after I received the ITF letter I found out that it also has another name, meldonium, which I did not know.
"It's very important for you to understand for 10 years this medicine was not on WADA's banned list and I had been legally taking the medicine for the past 10 years. But on January 1 the rules had changed and meldonium became a prohibited substance, which I had not known."
Sharapova would later say she began taking the medication, which can be used to treat heart issues, after irregular EKGs and being deficient in magnesium. Her family also has a history of diabetes, she added.
Her revelation came on the same day that Russia's Olympic ice dance gold medalist Ekaterina Bobrova said she failed a doping test for the same drug.
'I didn't click that link'
In a statement on its website, WADA said meldonium was prohibited because of evidence of its use by athletes "with the intention of enhancing performance." The anti-ischemic drug can aid oxygen intake and recovery.
WADA stated in September that the drug would be added to the prohibited list and Sharapova blamed herself for not taking note.
"I received an email on December 22 from WADA about the changes happening to the banned list and you can see prohibited items, and I didn't click that link.
"I made a huge mistake. I let my fans down and I let the sport down. I have been playing since the age of four a sport that I love so deeply.
"I know that with this I face consequences and I don't want to end my career this way. I really hope that I will be given another chance to play (tennis)."
Steve Simon, CEO of the WTA women's tour, was "saddened" by the development but said it was down to Sharapova to make sure she knew the rules.
"I am very saddened to hear this news about Maria," Simon, who became CEO in October, said in a statement. "Maria is a leader and I have always known her to be a woman of great integrity. Nevertheless, as Maria acknowledged, it is every player's responsibility to know what they put in their body and to know if it is permissible.
"This matter is now in the hands of the Tennis Anti-Doping Program and its standard procedures. The WTA will support the decisions reached through this process."
If she is given a full suspension, Sharapova would, easily, become the highest profile tennis player to be sanctioned.
