Wallabies flanker Dean Mumm has been cleared to face England at Twickenham on Saturday by a World Rugby independent disciplinary committee.
Mumm was sin-binned in the second minute of Australia's 27-24 loss to Ireland after a lifting tackle on Tadhg Furlong at Aviva Stadium and subsequently cited for the offence.
The 32-year-old appeared at a hearing in London on Tuesday where he was informed no further action would be taken against him.
The NSW Waratahs forward sat before a three-man disciplinary committee chaired by Welshman Simon Thomas, who accepted his argument that although the tackle warranted a yellow card it wasn't a red card offence and he should be free to play.
"It didn't meet the red card threshold and that was backed up by the disciplinary committee," Wallabies coach Michael Cheika said. "It was a good result."
