Teenage forward George Martin, who's played only seven senior games for Leicester, is in line for a shock England debut after being named on the bench for the Six Nations game against Wales in Cardiff.
Martin, 19, can play lock or in the back row and has been thrown into the Saturday's matchday 23 by coach Eddie Jones after Courtney Lawes was injured in training on Wednesday.
Martin joined the training squad last week after Jack Willis was ruled out of the rest of the tournament through injury.
There were no surprises in the starting team, despite England's stuttering start to the campaign that has brought defeat by Scotland and a win over Italy.
Jamie George returns at hooker with Mark Wilson replacing Lawes at blindside flanker.
Saracens duo Elliot Daly and Billy Vunipola, both struggling for form, retain their places - Daly winning his 50th cap - as does captain Owen Farrell, again starting at centre with George Ford at 10.
England fans have been clamouring for some of Jones's fringe youngsters to be given a chance but until the last few weeks Martin was not widely seen as one of those knocking on the door.
His selection marks the latest step in a meteoric rise for the bearded, 1.98m, 118kg youngster and is all the more surprising for the number of back rowers performing so strongly in the Premiership at the moment.
Jones has been conservative in selection so Martin's selection is somewhat of a surprise even given that he had been a stand-out performer as captain of England under-18s.
Seemingly, his ability to cover lock and back row, just as Lawes can, persuaded Jones he was the ideal man to step into the void.
