Tennis star Nick Kyrgios withdraws from Australia's Olympic squad over 'unfair and unjust' treatment

Tennis star Nick Kyrgios has withdrawn from Australia's Olympic squad. The rising star pulled out due to what he felt was "unfair and unjust" treatment from the Australian Olympic Committee.

Kyrgios becomes the second Australian tennis player to pull out following the withdrawal of Bernard Tomic. Both players were apparently placed on watch by AOC's chef de mission Kitty Chiller over their behaviour.

"It is with a heavy heart that I have had to make a decision not to compete at the 2016 Olympic Games in Rio de Janeiro. Coming to this decision has been a lengthy and difficult process, and I am extremely disappointed to have been put in this unfortunate position. I planned my tournament schedule around Rio and made sure to fulfill my Olympic eligibility. Unfortunately, while I have expressed every intention of trying to win a medal for my country in Rio, it's very clear to me that the Australian Olympic Committee has other plans", reads Kyrgios's statement.

"AOC's unfair and unjust treatment of me over the past few weeks, and unwarranted attacks on me demonstrate the organizations inability to understand the circumstances surrounding highly competitive sports. I also don't want the AOC's treatment of me to become a distraction and negatively affect the Australian team. I would like to wish every athlete representing Australia the best of luck this August and will be following their progress and supporting and cheering them from afar."

The 21-year-old has been involved in a number of issues related to his behaviour in the past, with Chiller particularly concerned about his girlfriend sledge against Stan Wawrinka that took place last year.

His sudden U-turn has baffled both fans and experts considering Kyrgios had reaffirmed his full commitment to the Australian Olympic Team in May, even launching an online poll asking fans whether they believe he should be on the plane to Rio.
