Wales Under 21 have lost Cardiff outside half Nicky Robinson to the senior Wales replacements bench at Twickenham following the injury to Stephen Jones.
And with the IRB Young Player of the Year, Swansea's Gavin Henson, ruled out with an injury, it means Newport's Michael Hook will win his first Under 21 cap in the No 10 jersey against England Under 21 at Newbury tonight (kick-off 7.30pm).
Wales will be seeking their fourth successive victory over England in the Six Nations Under 21 Championship. They also beat them in Argentina in an eight-team tournament in 2000.
England's only victory against Wales was in their first meeting in 1998 at
Worcester, winning 46-7.
In their Championship clashes, Wales won 36-21 at Neath in 1999, 15-12 at New Brighton in 2000 and 27-12 at Pontypridd last year.
After winning in Ireland and losing at home to France, Wales defeated Italy at Bridgend by 65-12. They have made a number of changes from that game, including bringing in Wales A No 8 Andrew Powell.
