Joe Launchbury has been cited for kicking Fiji centre Asaeli Tikoirotuma in England's 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.
England marched to their 12th consecutive win with a comprehensive 58-15 victory over the Fijians, with Launchbury scoring two of the home side's nine touchdowns.
