Serbian former world number 12 Viktor Troicki will appeal to the Court of Arbitration (CAS) against the 18-month ban slapped on him by the International Tennis Federation (ITF) for refusing to provide a blood sample at this year's Monte Carlo Masters.

"(I will be appealing) for sure," the 27-year-old said on his official website pleading innocence in the doping violation case. "I put my trust in the Court of Arbitration of Sports in Lausanne, I really hope they will look for the truth and find it, which is only one."
Misled
Troicki said he was misled by a doping control officer in Monte Carlo. "I gave the urine samples and told the doctor I was feeling really bad and I believed that drawing blood would make me feel even worse," said Troicki, who helped Serbia win the 2010 Davis Cup.
"The doctor in charge told me that I looked very pale and ill, and that I could skip the test if I wrote an explanation letter to ITF about it. She dictated the letter to me and let me go without giving blood."
An ITF statement said Troicki's actions constituted a "failure and refusal" to provide a blood sample and that his explanation for doing so was "not compelling."
