England and Northampton hooker Dylan Hartley will face a Rugby Football Union disciplinary hearing on Wednesday after being cited for foul play.
Hartley will appear before a three-man disciplinary panel in Coventry after he was reported for striking an opponent with his head during last Saturday's Aviva Premiership play-off game between Northampton and Saracens.
If banned, Hartley could be in danger of missing the Rugby World Cup later this year.
29-year-old Hartley has had a number of brushes with the rugby union establishment.
- April 2007 – Hartley was banned for 26 weeks after being cited for eye-gouging Wasps forwards James Haskell and Jonny O'Connor.
- March 2012 – he received an eight-week suspension after being cited for biting Ireland forward Stephen Ferris' finger while playing for England in a Six Nations game.
- December 2012 – he was banned for two weeks after being cited for punching Ulster hooker Rory Best during a Heineken Cup match.
- May 2013 - sent off for verbally abusing referee Wayne Barnes during the Aviva Premiership final against Leicester at Twickenham. Received an 11-week suspension that sidelined him for the British and Irish Lions tour to Australia, for which he had been selected.
- December 2014 - sent off for elbowing Leicester centre Matt Smith in the face. Banned for three weeks.
Hartley, who has won 61 England caps, has now been banned for a total of 50 weeks during his playing career.
