Handed a 21-month ban for failing a dope test, India gymnastics ace Dipa Karmakar on Saturday said she accepted provisional suspension after returning positive for a banned drug to swiftly resolve her case with the international federation.

Karmakar, however, claimed that she “unknowingly ingested” the prohibited substance Higenamine—S3 Beta-2 Agonists as per WADA prohibited list—which was found in her dope sample.  “...I unknowingly ingested and could not determine the source of [the banned substance]. I decided to take a provisional suspension with the hope of a swift resolution with the international federation,” Karmakar tweeted, indicating that she had admitted to the doping rule violation.
