Janik Sinner, the No. 1 ranked men’s tennis player, will be sanctioned — but not suspended — after twice testing positive for an anabolic steroid earlier this year.

Sinner tested positive on March 10 for clostebol after the hard-court event at Indian Wells, then tested positive again eight days later after an out-of-competition test. Sinner was provisionally suspended but he appealed, allowing him to continue playing during an investigation. The inquiry by the International Tennis Integrity Agency revealed Sinner ingested the substance accidentally.

“I will now put this challenging and deeply unfortunate period behind me,” Sinner said Tuesday in a statement on Instagram. “I will continue to do everything I can to ensure I continue to comply with the ITIA’s anti-doping programme and I have a team around me that are meticulous in their own compliance.”

According to the ITIA, Sinner explained that the substance entered his system due to contamination from a support team member who had been applying an over-the-counter spray containing clostebol to their own skin to treat a small wound.

The substance made its way into Skinner after receiving massages and therapy from the team member.
