Hughes to miss majority of Autumn Internationals following concurrent bans following Ludlow punch and controversial tweet.
Wasps and England number eight Nathan Hughes has been handed two bans covering a six week period.
The 17-times-capped backrower is free to return to play on the 20th of November, four days before England face Australia at Twickenham.
The first of Hughes' two suspensions will last six weeks, having been found guilty of striking Gloucester flanker Lewis Ludlow.
The second ban, which will run concurrently with the first, will last for two weeks following the Fijian-born player's Tweet during the final phases of the initial hearing last week (Wednesday, 10th October).
Hughes, 27, sent out a Tweet reading "What a joke" in reaction to his month-long suspension, for which he was found guilty of infraction contrary to RFU Rule 5.12.
The club - and Hughes - were advised that the usual process would be followed in respect of the issuing of a press release but that, in the interim, there was to be no comment on social media.
Having initially been permitted a two week reduction for his guilty plea, remorse and good conduct, the panel found that Hughes' mitigation had been given on "a false premise", admitting that his original guilty plea had only been entered on advice and did not believe that he was guilty of the offence in question.
Additionally, the disciplinary panel made a statement regarding the nature of Hughes' publicly expressed distress on Twitter, commenting: "The Panel make it clear that tweets and comments such as this undermine the Game, the core value of respect and the disciplinary process.
"Whilst players and clubs are entitled to disagree with the outcome of disciplinary hearings, there are proper processes to be followed and twitter, or social media more generally, are not the appropriate forums for such frustration to be vented."
