Wales prop Henry Thomas has been ruled out of the international against world champions South Africa on Saturday at Twickenham because of a foot injury.

Wales v South Africa: Cameron Winnett; Liam Williams, Owen Watkin, Mason Grady, Rio Dyer; Sam Costelow, Ellis Bevan; Gareth Thomas, Dewi Lake, Keiron Assiratti, Matthew Screech, Ben Carter, Taine Plumtree, James Botham, Aaron Wainwright.

Scarlets hooker Ryan Elias has been rested for the summer programme with Dewi Lake, Evan Lloyd and Sam Parry the other specialists named in the official extended training squad.

Cardiff hooker Efan Daniel has been called into train with Wales and is now in contention to travel to Australia alongside Lake and Lloyd.
