Rugby-Giteau, Mitchell in Wallabies squad for Rugby Championship

MELBOURNE, July 2 (Reuters) - Australia coach Michael Cheika has included France-based backs Matt Giteau and Drew Mitchell in his 40-man training squad for the Rugby Championship against New Zealand, South Africa and Argentina. The Toulon team mates became eligible to play for the Wallabies after a rule change earlier this year which allowed overseas-based players with 60 international caps to be selected. Cheika has also included four uncapped players -- Melbourne Rebels prop Toby Smith, ACT Brumbies lock Rory Arnold, Queensland Reds centre Samu Kerevi and New South Wales Waratahs winger Taqele Naiyaravoro -- in his squad named on Thursday. Long-serving flanker George Smith has been omitted as has experienced outside back James O'Connor.
