#4. Danny Grewcock – 28 weeks
A second row with something of a short fuse. Picked up a five-week ban after being sent off for kicking All Blacks hooker Anton Oliver in a Test in Dunedin in 1998, two weeks for punching Lawrence Dallaglio in a club match in 2003, two months for biting All Black hooker Keven Mealamu during the first Lions Test in 2005, six weeks for punching French lock Thibault Privat in 2007 and seven weeks for stamping on Ulster flanker Stephen Ferris in 2010. Knew his way to the disciplinary offices!
