World number two and five-time Grand Slam champion Iga Swiatek has accepted a one-month suspension after testing positive for a banned substance.
The 23-year-old reigning French Open champion tested positive for a heart medication, trimetazidine (TMZ), in an out-of-competition sample in August 2024, when she was world number one.
The International Tennis Integrity Agency (ITIA) confirmed on Thursday an investigation determined the source was a contaminated regulated medication.
It therefore ruled Swiatek bore no significant fault or negligence for the failed test.
The Polish player was provisionally suspended from 12 September before successfully appealing, missing three tournaments.
With Swiatek's level of fault considered to be at the lowest end of the range for 'No Significant Fault or Negligence', the ITIA offered a one-month suspension which she accepted on Wednesday.
As Swiatek was provisionally suspended until 4 October, a further eight days of her ban remain.
The Pole was also forced to forfeit the prize money from her run to the Cincinnati Open semi-finals, the tournament that directly followed the test.
