Former Scotland international Jim Hamilton and Clermont legend Jamie Cudmore are regarded as two of the toughest and dirtiest players of the modern era.
The pair played in the second row and acted as enforcers on the field throughout their careers which saw them spend a lot of time in the sin bin.
Hamilton played 63 times for Scotland and retired in 2017. He was notorious for his physicality and got involved in scraps with some of the biggest players in the game and threw an infamous right hook to the face of David Paice back in 2012.
Cudmore, who also played his last professional match in 2017, made 43 appearances for Canada but was best known for his 11 years with Clermont Auvergne.
The Canadian stands at 6ft 5”, three inches shorter than Hamilton, but weighs around 120kg which he threw around the pitch consistently.
