The 30-year-old tested positive for the banned drug letrozole, a drug which is associated with female body builders as it can increase body mass.
A tribunal set-up by the Tennis Anti-Doping Programme ruled that there was no evidence of deliberate cheating. She will, however, also lose the rankings points and prize money that she had earned between Feb 16 and her most recent dope test on June 7, which found nothing untoward.
The former world number five will be out of action for the next two months meaning she will be out of the US Open at Flushing Meadows later this month. Mrs Errani - who has suffered multiple incidences of cancer in the past - kept the chemical in a blister pack of pills, which she would leave to the side of her kitchen worktop.
At a hearing on 19 July 2017, the Independent Tribunal received evidence and heard legal arguments from both parties, and subsequently issued a reasoned decision on 3 August, which is available at www.itftennis.com/antidoping. The circumstances are unusual as Errani tested positive for letrozole, a drug her mother was using to treat breast cancer.
In a statement posted on her Twitter page, she wrote: "I never took, in my life and during my career, any prohibited substance".
On the flip side, this could also just be a way to make it seem like they are taking a more serious stance against drugs by using a known but not highly ranked professional, who in this case is Sara Errani.
"The only viable option has been that an accidental food contamination occurred".
"I am extremely disappointed but at the same time at peace with my conscience and aware I haven't done anything wrong, neither have I committed any negligence against the anti-doping program".
Errani was informed that she had failed a drugs test on April 18th, meaning that she played during the clay court and grass court season after being informed of a potential suspension. Contamination was possible because there had been times when pills had been dropped or spilled.
