Former Wimbledon runner-up Nick Kyrgios has been provisionally suspended from tennis after failing a doping test, the International Tennis Integrity Agency (ITIA) announced on Wednesday.

The 31-year-old Australian gave a sample at an ATP tournament in Mallorca in June that tested positive for benzoylecgonine, a metabolite of cocaine, the ITIA said.

Cocaine is classified as a stimulant and substance of abuse on the World Anti-Doping Agency (WADA) Prohibited List and is banned in competition.

Kyrgios apologized to his fans in a statement on social media, saying he took full responsibility.

"I made a huge mistake," he said. "I'm sorry to my fans, my family, my sponsors and everyone close to me. Above all, I'm sorry to the kids who follow me. I know the example this sets and I'm deeply disappointed in myself."
