England coach Eddie Jones has added uncapped Worcester Warriors hooker Jack Singleton in the squad for the second Test against South Africa.
The 22-year-old will provide cover to Exeter Chiefs' Luke Cowan-Dickie after the latter sustained a hamstring injury during the first game in Johannesburg which England went on to lose 42-39.
Singleton made his professional rugby debut with Harpenden RFC, and while playing for U18s he won the National Cup on his last game for the club.
He moved to Worcester Warriors from Saracens in 2014 and has gone on to play 31 English Premiership games for the Sixways outfit since 2016.
The final two Tests between the two teams will be played in Bloemfontein and Cape Town on 16th and 23rd June respectively with South Africa having a 1-0 lead.
