Five-time Grand Slam champion Iga Swiatek has accepted a one-month suspension after testing positive for the banned substance trimetazidine.

Meanwhile, Swiatek was found to have been “at the lowest end of the range for no significant fault or negligence” after the 23-year-old Polish player explained that her doping violation was caused by a contaminated supply of the non-prescription medication melatonin, which she uses to help with jet lag and sleep issues.
