A day after the bombshell news surrounding the world's richest female athlete -- the five-time grand slam winner's estimated net worth is $195 million -- we answer five key questions in the case.
So Sharapova admitted to failing the drug test. When will we find out her punishment?
Serbia's Viktor Troicki, for example, refused to take a blood test in April 2013 at a tournament in Monte Carlo and when the ITF announced his punishment, it came in late July of the same year.
Marin Cilic's urine sample showed a banned substance when he was at a tournament in Munich in late April 2013. In sanctioning the Croatian, who won the U.S. Open in 2014, the ITF announced his penalty five months later, in September.
The complexity of cases is a factor, as is the evidence that needs to be examined.

What kind of punishment could Sharapova get?
Banned substances are broken down into non-specified and specified. Meldonium falls into the former category and for a first-time offender like Sharapova, she can be hit with a four-year ban.
However, there is a way for the four-year suspension to be reduced, if it is established that the anti-doping rule violation wasn't intentional. In that case, the most likely ban is two years.

Sharapova certainly suggested it wasn't intentional, claiming she started taking the drug in 2006 for poor health. According to the 28-year-old, several of her electrocardiography (EKG) tests were irregular and she was magnesium deficient.
What is meldonium and when did it become a prohibited substance?
Meldonium is an anti-ischemic drug that is often used to treat heart issues.
The World Anti-Doping Agency (WADA), which formulates the list of banned substances followed by major sports bodies around the world, didn't have it on its prohibited list prior to 2016.
Why was it added this year, then, under metabolic modulators?
"Meldonium was added (to the prohibited) list because of evidence of its use by athletes with the intention of enhancing performance," WADA said on its website.
It may boost endurance and aid in the recovery process.
Another website, cleancompetition.org, revealed last October the results of a research project it partly funded which found 182 or 2.2% of 8,300 urine samples collected from athletes contained mildronate, also known as meldonium.

"From an anti-doping perspective, the 2.2% rate in this study was concerning," Larry Bowers, chairperson of the Partnership for Clean Competition's scientific board, told the website.
"This figure represents more than twice the overall rate of laboratory findings for a single drug than any of the substances on the Prohibited List."
That Sharapova didn't check the updated list raised eyebrows. More surprising is the fact that, according to her lawyer John Haggerty, no one on her team did, either.
"Unfortunately no one from Maria's team looked at the 2016 banned list but had they done so they would have looked for mildronate and not found it on the list," Haggerty wrote in an email to CNN.
