Quade Cooper has been left disappointed by his sin-binning in the Wallabies' World Cup win over Uruguay, with coach Michael Cheika confirming an appeal would be lodged.
The 27-year-old was sent to the sin-bin for tackling Uruguayan No.9 Agustin Ormaechea high and then body-slamming him into the turf.
It is Cooper's third yellow card in his past four tests - with sin-bins also coming against Argentina and New Zealand.
All three offences have been high tackles, perhaps suggesting a need to refine his technique.
"It was disappointing to be sin-binned as it was such an awesome atmosphere out there," Cooper said.
"I am not sure on what's going to happen now, it's hard for me comment on that.
"I will just wait and see how it unfolds and continue to prepare and get better each day."
Cooper's goal-kicking, too, was off target - and his return of five from 11 attempts is unlikely to put pressure on Bernard Foley, although his ability to set up three tries might.
With ball in hand, Cooper looked a constant threat albeit against a semi-professional side in Uruguay.
Having regathered a Beale midfield grubber, Cooper produced a superb flick pass for Joe Tomane to cross for the Wallabies' second try.
He was in the thick of things for Drew Mitchell's second try - throwing a pinpoint cut-out pass to to hit the winger on the chest.
It's why he shouldn't be discounted for Saturday's crucial Pool A match with England at Twickenham - despite Foley having one foot in the door already.
Should a player accumulate three yellow cards through tournament play, he would earn a one-game suspension, which is why Cheika confirmed the Wallabies would be fighting Cooper's yellow.
"We will appeal that," Cheika said.
"I feel like that hit was across the shoulder."
