Saracens winger Chris Ashton has been charged with two acts of biting by the Rugby Football Union and will appear before a disciplinary panel on Tuesday.
The 29-year-old, capped 39 times by England, is alleged to have bitten Northampton prop Alex Waller during Saturday's 27-12 Aviva Premiership victory.
The two incidents occurred in the 24th and 25th minute of the clash at Allianz Park with Ashton’s mouth appearing to make contact with Waller’s hand during a tangle on the floor.
Ashton will appear before an RFU disciplinary panel chaired by Philip Evans QC, and also including Tom Rees and Paula Carter, in London.
