Alex Mitchell and Jonny May will start for England in their World Cup opener against Argentina despite initially missing out on the 33-man squad.

George Ford will start at fly-half with captain Owen Farrell banned for the first two pool games.

Flanker Tom Curry starts his first game since the Premiership final in May.

Open-side Curry, who started the 2019 World Cup final defeat by South Africa, is yet to feature for England this summer after recovering from an ankle injury.

Ben Earl replaces Saracens team-mate Billy Vunipola, who is suspended for the opening game following his red card against Ireland in England's penultimate warm-up game, at number eight.

Courtney Lawes completes the back row on the blind-side and continues as captain in the absence of Farrell.

Veteran prop Dan Cole starts at tight-head with Bath's Will Stuart named amongst the replacements.

Wing Elliot Daly has recovered from a knee injury to join 33-year-old May, who has 73 caps, and regular full-back Freddie Steward in the back three.

Harlequins' Joe Marchant partners Manu Tuilagi in the midfield - as they did in the defeat by Ireland in Dublin.

Replacement scrum-half Danny Care, 36, is given the nod over Leicester Tigers' Ben Youngs on the bench in what could be only his second World Cup appearance, having made his first against Uruguay in 2015.

England, who are ranked eighth in the world, lost three of their four warm-up games heading into the World Cup.

Borthwick's side also face Japan, Chile and Samoa in Pool D, with the top two sides progressing to the quarter-finals.

Mitchell wildcard

Prior to his injury, Leicester Tigers' Van Poortvliet had been Borthwick's favoured scrum-half, having started every game in the Six Nations, with the 22-year-old known for his strong kicking game.

Mitchell, 26, who is more of a running scrum-half, scored seven tries in the Premiership last season, but missed out on the initial 33-man squad.

However, he started England's final warm-up game against Fiji, winning only his sixth cap, as Borthwick favoured him ahead of veteran scrum-halves Care and Youngs.

With just five tries in four warm-up matches, England's attack may require more energy and dynamism, and Mitchell can help create "organised chaos" according to former England international Ugo Moyne.

Line-up

England team to face Argentina: Steward; May, Marchant, Tuilagi, Daly; Ford, Mitchell; Genge, George, Cole; Itoje, Chessum; Lawes (capt), Curry, Earl.

Replacements: Dan, Marler, Stuart, Martin, Ludlam, Care, Smith, Lawrence.
