Heaviest rugby player of all-time was over 25 stone (Top 10 ranked)

 for good reason, Ntlabakanye muscled his way into the Springboks set-up in 2024 after folding scrums for the Lions.

These are the giants who made referees blink twice at the team sheet, battered scrum machines into submission and had entire packs questioning whether the laws of physics were still in force.

Forget post-Christmas excess — this is heavyweight rugby at its absolute limit.

The latest juggernaut off the famous Tuilagi production line. Already a Test lock for France and flattening anything in front of him for Perpignan, Posolo brings the family’s trademark destruction to the engine room.

At nearly 150kg, he moves alarmingly well for his size, making him less “big unit” and more “rolling natural disaster”.

Nicknamed Ox Lite

A tighthead built like a concrete mixer, his game is brutally simple: dominate collisions, crush the set-piece and leave looseheads in survival mode. Still developing — already frightening.

A modern front-row great. With over 70 Test caps, a Six Nations title and multiple European trophies with La Rochelle, Atonio has been a cornerstone of French success for over a decade.

At 155kg, he remains the definition of immovable — an anchor who makes even elite scrummagers look lightweight.

The modern monster prop. Tonga captain, long-time scrum anchor and cult hero across hemispheres, Tameifuna combines jaw-dropping mass with soft hands and deceptive footwork.

From Super Rugby stardom with the Chiefs to European dominance with Racing 92 and Bordeaux, he’s proof that sheer size can still come with skill.

The undisputed heavyweight king of rugby. A cult figure of the early 2000s, Cavubati famously packed down against the All Blacks in 2005 weighing more than some backlines combined.

A Wellington stalwart and Hurricanes squad member, he wasn’t just big — he could actually scrum, which makes his size all the more ridiculous.
