England have not called up any extra props to cope with the loss of Mako Vunipola ahead of the Wales match as Ellis Genge and Ben Moon were retained for a training camp.
Alec Hepburn might have been the next loosehead prop to be called up in the absence of the supreme Vunipola, who was ruled out for 10 weeks with an ankle ligament injury on Tuesday, but the Exeter Chief will stay in Devon.
