Ireland may not have the biggest pack at this year's Rugby World Cup - but they will have plenty of heft in their scrum.
The heaviest of the 31-man squad heading to Tokyo is Leinster prop Andrew Porter who is a 19st 2lbs power machine.
Porter, 23, impressed in the World Cup warm-up matches and will be keeping regular starters Tadhg Furlong and Cian Healy honest.
The second heaviest is also the tallest - Munster second row Jean Kleyn - who controversially edged out Devin Toner to make the final squad.
The lightest player in the squad is Leinster scrum-half Luke mcGrath (12st 10lbs) who is also the shortest at 5'9.
The ten heaviest:
1. Andrew Porter (Leinster) 19st 2lbs
2. Jean Kleyn (Munster) 19st 0lbs
3. John Ryan (Munster) 18st 10 lbs
4. Tadhg Furlong (Leinster) 18st 8 lbs
5. Iain Henderson (Ulster) 18st 4lbs
6. CJ Stander (Munster) 17st 11lbs
7. Tadhg Beirne (Munster) 17st 9lbs
7. James Ryan (Leinster) 17st 9lbs
9. Cian Healy (Leinster) 17st 7lbs
10. Rhys Ruddock (Leinster) 17st 5lbs
10. Niall Scannell (Munster) 17st 5lbs
