Sydney - Troubled tennis star Bernard Tomic announced on Friday he will not represent Australia at this year's Olympics, with unperturbed officials responding that they only want dedicated athletes on their Rio team.
It follows Tomic and fiery compatriot Nick Kyrgios being warned that their on-court behaviour could threaten their places at the Games in August.
World number 22 Tomic will instead play a low-ranking ATP Tour event in Mexico, which is on at the same time.
