Australian coach Andy Friend has stressed throwing Quade Cooper into the sevens' deep end would have disrespected his regular campaigners and sacrificed Sydney 7s success.
In his first tournament in charge of the Thunderbolts, Friend has caused an outcry by overlooking the Wallabies showman after he flew from France expressly to make his sevens debut.
But Cooper was told once he stepped off the plane, a week late, on Wednesday morning he was next to no chance of playing due to a limited preparation which put undue risk on his body.
Friend also reasoned just one full training session with his new team was not enough to ensure the 58-Test playmaker, as talented as he is, would add value to the hard-scrapping Australians.
"We've got a lot of young blokes here who have worked their backsides off," he said on Friday.
