Pitting together in a physical battle two people with weights differing by as much as 13 Stone is surely nothing short of cruel, but that could happen at the Rugby World Cup, with players ranging from as little as 10 stone up to nearly 23. Here, we take a look at the 10 biggest players that could take to the field later this month.
Johnny Redelinghuys - 20st
At only just over six feet, Nambian prop Redelinghuys is an absolute tank, accordingly extremely difficult to half once he gets going. With bags of experience, he has 25 points in 48 games for his country and will again prove a real handful.
Mike Ross - 20st
Ireland veteran Mike Ross, right, also weighs in at 20 stone and he too provides a wealth of experience on top of adding weight to the pack. How many full games he manages at the ripe age of 35 remains to be seen but he will still provide plenty of presence.
Charlie Faumuina - 20st 2lb
According to a former coach of the 128kg, 6ft New Zealand prop, Faumuina has 'footwork like a ballerina'. He is impressively agile, yes, but don't expect to see him doing actual ballet any time soon.
Abel de Klerk - 20st 2lb
Namibia might not have history on their side but they certainly have size, with another of their props making the top 10. De Klerk is marginally heavier than Redelinghuys but, remarkably, is only 5'10" tall, making him more than 3 inches shorter than the tournament average of 6'1", despite being the seventh heaviest.
Tomas Francis - 20st 6lb
One of the least experienced members of any Rugby World Cup squad, Francis has only two caps to his name but he will dwarf most of the players he comes across nonetheless. Over 20 stone and 6'2" tall, he is a significant presence, even if he is only 23 years old.
Horace Pungea - 20st 6lb
Prop Pungea is a seriously intimidating presence in the Romanian squad and he won't back down from any battle with only two players actually heavier than him at the World Cup.
Leroy Atalifo - 20st 6lb
Also equal in weight, Atalifo of Fiji is as chunky as they come. At 5'10" and 130 kilos, few are more powerful than him: he has only two substitute appearances for Fiji but already has one try to his name.
Ramiro Herrera - 20st 6lb
The gigantic Herrera has only in the past year or so established himself on the international scene. Strange, seeing as it is hard to see how he wasn't previously noticed. A 6'3" powerhouse, he looks like he has been helped by a steak or two from his native Argentina.
Will Skelton - 22st
Incredibly, 6'8" Australia lock Will Skelton is only the eighth tallest player going to the Rugby World Cup. Even more shocking, he is only 23 years of age. Less surprisingly, he is the second heaviest at the tournament, weighing in at a whopping 140 kilograms.
Uini Atonio - 22st 11lb
Way out in front as the heaviest player at the upcoming Rugby World Cup, New Zealand born France international Uini Atonio is the biggest of them all. Quite a sight on his own at nearly 6'6" tall, one has to wonder how opponents ever manage to take him down. If France meet Samoa at some stage, it could be 65kg scrum half Vavao Afemi who has to try and tackle 145kg Atonio. The bigger they are, the harder they fall...
