Wallabies flanker Michael Hooper is in doubt for Australia's Rugby Championship decider against the All Blacks in Sydney after being cited for alleged foul play in Australia's 34-9 win against Argentina on Sunday.
Hooper was cited by SANZAR on Sunday night, 12 hours after the Wallabies' bonus-point victory over the Pumas in Mendoza.
The former skipper is alleged to have contravened a law involving punching or striking, when he made contact with Argentina first five-eighth Nicolas Sanchez in the 59th minute of the Test.
