(Reuters) - Australia's Bernard Tomic ruled himself out of consideration for the Rio Olympics on Friday due to an "extremely busy" playing schedule, with the world number 22 saying he would play an ATP tournament in Mexico instead.

Tomic and Nick Kyrgios were warned by Australia's Olympic chef de mission Kitty Chiller at the weekend that they were among a group of athletes whose behaviour was being monitored to judge their suitability for the Rio team.
