Leicester centre Ollie Smith has been called into Sir Clive Woodward's northern hemisphere squad for the tsunami aid relief match at Twickenham.
The 22-year-old is desperate to use Saturday's star-studded fundraiser to prove his Test credentials to England head coach Andy Robinson.
Smith was overlooked by England for the first two RBS 6 Nations games and was an unused substitute for last weekend's defeat by Ireland in Dublin despite being in prime form.
''Unfortunately I wasn't able to get on against Ireland but hopefully I can prove myself in this match, which is for a worthwhile cause, and force my way into the England starting XV,'' he said.
''I was meant to have a week off, but when I got the call I jumped at the opportunity to play in a match like this and, of course, to play alongside some terrific players and work under Clive Woodward again.''
Smith joins Ben Cohen and Lawrence Dallaglio as England's representatives in a squad to be captained by Ireland centre Brian O'Driscoll.
The southern hemisphere squad for Saturday's match includes captain George Gregan and All Blacks skipper Tana Umaga.
England Under-18 head coach John Fletcher insists his young side will be better for the experience after beating Italy in the bronze final to round out their 2015 Rugby Europe U18 Championship campaign in style.
