Bath Rugby's Elliott Stooke and Zach Mercer have both been selected to start for England ahead of Sunday's Quilter Cup match against the Barbarians at Twickenham (Kick-off 15:00).
Head coach Eddie Jones said: “This is a good young squad and their work ethic has been outstanding over the last two weeks. Their application to learn has been very good but they are very young at Test rugby level so this week’s match against the Barbarians is a fantastic opportunity for them to step up.
“It is a great opportunity for them to show they deserve to wear the English rose, to show they can be in contention for the World Cup and a great opportunity for them to put us on the front foot ahead of the South Africa tour.
“You never know what to expect from the Barbarians team. We know they will be well coached by Pat Lam, we know they have got good individual players and some outstanding individual players, so we need to be up for the unexpected.
“As last year Chris Robshaw and George Ford will co-captain the side.Their combined experience and expertise gives us the best captaincy level for the game.
“We can’t wait to get back to Twickenham and get on the front foot, please the fans and play some good rugby.”
