The world anti-doping agency won't appeal against the one-month suspension given to five-time Grand Slam champion Iga Swiatek.
She tested positive for the banned substance TMZ in an out-of-competition sample last August.
WADA says it accepts the International Tennis Integrity Agency's findings that the failed drugs test was a result of contamination.
Meanwhile, Swiatek was on court earlier beating Germany's Eva Lyse in straight sets to reach the quarter-finals of the Australian Open.
She will be joined by Elena Svitolina, Madison Keys and Emma Navarro who all won their last 16 clashes.
