The World Rugby rankings could be set for a big shake-up this weekend and one series of results could see Ireland move to the number one spot.
It all hinges on whether New Zealand can bounce back from their 47-26 loss against Australia last week. The All Blacks are on a quest for revenge as they take on Michael Cheika's outfit at Eden Park.
The other crucial game is England versus Wales as Eddie Jones looks to complete back-to-back victories. If they draw in Cardiff and Australia win or draw in the other game, Ireland would take top spot.
Alternatively, if Wales win or England win by 16 points or more, either of them would move to world number one.
As of right now, New Zealand remain number one with Six Nations champions Wales in second and Ireland in third.
Joe Schmidt's outfit are currently in Portugal for a warm-weather training camp ahead of their second warm-up game against England next week.
Elsewhere in the rankings, Ireland's World Cup group opposition and the tournament hosts Japan are now the biggest climbers to ninth after a series of strong showings saw them defeat Fiji, Tonga and USA.
