The Rugby World Cup is a birthplace for stars, a platform for greats in their prime and a final port of call for legends looking to sign off their careers on a high.
For veterans like South Africa's Victor Matfield, Ireland's Paul O'Connell, New Zealand's Kevan Mealamu and Italy's Mauro Bergamasco, this is likely to be their last appearance at the tournament before they retire.
Here is a list of some the oldest players to feature at a World Cup…

The Teros' number eight and captain was 40 years and 26 days old when he played against South Africa at the 1999 tournament; making him the oldest player in the competition's history. He scored in the 27-15 win over Spain and later coached Uruguay at the 2003 edition, where they beat Georgia 24-12.
