Tennis star Iga Swiatek accepts 1-month suspension for banned substance

The ITIA accepted her explanation that the results weren't intentional, saying it was caused by contamination of a nonprescription medication, melatonin, which she uses for issues with jet lag and sleeping. 

The ITIA stated that Swiatek's level of fault was "at the lowest end of the range for no significant fault or negligence."

Swiatek was previously suspended from Sept. 12 to Oct. 4, missing three tournaments over that span - Korea Open, China Open and Wuhan Open - though she said at the time it was due to personal reasons.

Swiatek has only eight days remaining on the punishment, which will be served while there's no competition.

So, she will be cleared to return on Monday. 

Along with the suspension, Swiatek has to forfeit $158,944 of prize money from the Cincinnati Open, which she played in after failing the test. She ultimately lost in the semifinals.

In an Instagram video, Swiatek reacted to the ITIA's decision, calling it the "worst experience of my life."

"In the last two and a half months, I was subject to strict ITIA proceedings, which confirmed my innocence," Swiatek said in the video. "The only positive doping test in my career, showing unbelievably low level of a banned substance I've never heard about before, put everything I've worked so hard for my entire life into question.

"Both me and my team had to deal with tremendous stress and anxiety. Now everything has been carefully explained, and with a clean slate I can go back to what I love most."
