UNCAPPED Worcester Warriors hooker Jack Singleton will join England’s squad in South Africa as cover for Luke Cowan-Dickie.

England have confirmed Singleton, 22, has been called up as a "precaution" after Exeter Chiefs front rower Cowan-Dickie "experienced hamstring tightness" following their 42-39 defeat in Johannesburg.

Singleton featured in the recent non-cap game against the Barbarians at Twickenham and toured with Eddie Jones' squad to Argentina last year.

England are preparing for the second Test match in Bloemfontein on Saturday.
