Former Wimbledon finalist Nick Kyrgios was provisionally suspended from tennis on Wednesday after testing positive for cocaine, with the volatile Australian owning up to his ¡°huge mistake¡± in a public apology.

The International Tennis Integrity Agency (ITIA) announced the suspension of the 31-year-old following a positive test for benzoylecgonine, a cocaine metabolite, from a sample taken during an ATP 250 event in Mallorca in June.

Kyrgios, who reached a career-high rank of No. 13, has been provisionally suspended since Aug.?4 after a World Anti-Doping Agency (WADA) laboratory confirmed the presence of the banned stimulant on July 17.
