London Wasps have been given a lift with Joe Launchbury set to start his first Test for England in Saturday's third QBE International against South Africa at Twickenham Stadium.
The 21-year-old lock - regarded as an outstanding prospect - has impressed when coming off the bench against Fiji and Australia and gets his chance in a side showing six changes.
Launchbury has featured in both of Wasps' Amlin Challenge Cup matches this season, scoring a try against Rugby Mogliano, as the 2003 tournament champions have claimed top spot in Pool 3 ahead of their key back-to-back contests with second placed Bayonne next month.
A second Wasp makes the match day squad with James Haskell named on the replacements bench while Tom Wood (Northampton Saints) and Ben Morgan (Gloucester Rugby) take over from Tom Johnson and Thomas Waldrom at No 6 and 8 respectively, while Alex Corbisiero comes in for Joe Marler at loosehead prop.
Mike Brown (Harlequins) replaces Charlie Sharples on the left wing and Ben Youngs partners Leicester Tigers' team-mate Toby Flood at halfback.
There are also call-ups to the bench for the first time in this series for Haskell, Mouritz Botha and Jonathan Joseph.
England Head Coach Stuart Lancaster said: "We have picked a team that will give us the best chance of beating South Africa.
"There were some tight calls, which is what you want as coaches, but the players we have brought into start have been training well, will bring a real motivation to make the most of their opportunity and will suit the challenge we face against a tough and physical South African team."
As part of the build-up to next month's Cardiff 2014 Heineken Cup and Amlin Challenge Cup finals weekend, ERC has joined forces with the WRU, Cardiff Blues and adidas to develop an annual grassroots community rugby programme targeting young players.
The Ulster Rugby full back, Jared Payne (No 15), has been suspended for two (2) weeks following an independent Disciplinary Hearing in Dublin arising from the Heineken Cup quarter-final match against Saracens at Ravenhill Stadium on Saturday, 5 April.
