The inaugural Nations Championship's first phase concludes with 12 leading sides finishing a busy July. South Africa, New Zealand, and Ireland lead with two wins each. Ireland face New Zealand at Eden Park, where no team has won since 1994. Sam Prendergast, 23, starts at fly-half for Ireland, aiming to stake a claim over Jack Crowley.

France travel to Tokyo to face Japan, with young fly-half Ryunosuke Ito backed by Eddie Jones. Fiji, disrupted by Mick Byrne's departure, host Scotland at Murrayfield after poor showings. Vusi Moyo, 20, debuts at fly-half for South Africa against Wales, potentially challenging Handre Pollard and Manie Libbok.

Argentina face England in Santiago del Estero, with tension from November's Twickenham tunnel incident involving Tom Curry. England seek a third straight summer win against the Pumas under Steve Borthwick.
