England lock Joe Launchbury has been cited for kicking Fiji centre Asaeli Tikoirotuma in the 58-15 victory at Twickenham on Saturday.
The incident is alleged to have taken place in the second minute with Launchbury appearing to aim for the ball only to strike Tikoirotuma.
The low-end sanction for the offence is four weeks, the mid-range eight weeks and the top-end 12 weeks plus, with Launchbury's hearing scheduled for Monday afternoon.
Launchbury crossed twice in the nine-try demolition of Fiji but could now miss the remaining two matches of England's autumn program, against Argentina on Saturday and Australia on December 3.
The Wasps captain has started alongside Courtney Lawes for the comfortable wins over South Africa and the Pacific Islanders due to the injury enforced absence of Maro Itoje and George Kruis.

However, Kruis' return from ankle surgery is imminent therefore mitigating the disruption caused if Launchbury is suspended, although coach Eddie Jones will not want to be denied the use of one of his top performers this autumn.
