Former England captain John Terry unexpectedly ended his nine-year international career on Sunday, quitting before he was due to face a racism hearing because his place in the team had become "untenable."

Wallabies flyhalf Quade Cooper has described the environment within the Australian team as "toxic" in the latest of a series of public comments which appear to challenge the authority of coach Robbie Deans and the Australian Rugby Union.

Cooper, who is sidelined for several weeks after knee surgery, began to post a series of Twitter comments from Thursday which appeared to criticize the conservative style the Wallabies have adopted under Deans. Cooper drew a contrast with the more open style he is able to play at the Queensland Reds Super 15 team, under former Wallabies assistant coach Ewen McKenzie.
