Joe Marler is now set to be available for England’s second autumn international against Australia.
The decision to spread the looseheads three-week ban over a four-week period expected to be reversed today.
Marler was initially suspended for striking on Wednesday, but a European Professional Club Rugby disciplinary committee judged that because of the player’s “likely playing commitments” the ban would not include Harlequins’ Anglo-Welsh Cup clash with Saracens on 5 November.
The prop was therefore ruled out of matches against Argentina and Australia and not selected in head coach Eddie Jones’ squad.
But it is understood Harlequins have successfully queried the verdict with the European Cup authorities.
It means Marler will be free to face the Wallabies on 18 November, if selected.
England face Argentina on 11 November, Australia on 18 November and Samoa on 25 November.
