Dylan Hartley in numbers

Dylan Hartley has been named as England's captain for the RBS 6 Nations.

The Northampton hooker missed last summer's World Cup after being axed from England's training squad when he was hit with a four-week ban for a headbutting offence during the Aviva Premiership semi-finals.

That was one of a series of on-field disciplinary issues that have blighted the 29-year-old's career, with his various suspensions seeing Hartley banned for a total of 54 weeks

:: April 2007 - banned for 26 weeks after being cited for eye-gouging Wasps forwards James Haskell and Jonny O'Connor.

:: March 2012 - 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 - 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 which he had been selected for.

:: December 2014 - sent off for elbowing Leicester centre Matt Smith in the face. Banned for three weeks.

:: May 2015 - banned for four weeks after headbutting Saracens' Jamie George in Northampton's 29-24 Aviva Premiership semi-final defeat to Saracens. As a direct consequence, England ruled Hartley out of their World Cup plans.
