Worcester Warriors up and coming back row Matt Cox is one of two changes as England prepare to face South Africa in the semi-finals of the IRB Junior World Championships tonight (Wednesday).
Cox comes in at flanker in place of John Fisher as England Under 20s named the side that they hope will book a final spot in the clash at Cardiff Arms Park (kick-off 9.10pm).
Worcester wing sensation Miles Benjamin, whose brace stunned Australia in the last game, is named while the other changes see Alex Tait come in at full-back for Noah Cato, who switches to the other wing, and Ben Thomas in the pack.
England are unbeaten in eight games at Under 20 level this season, scoring 38 tries in total, after completing a Six Nations Grand Slam and beating Fiji (41-17), Canada (60-18) and Australia at the Junior World Championship.
New Zealand take on hosts Wales in the other semi-final at Swansea (7pm) and both games are being shown live on BBC Wales.
