England have been forced into a late change of plan for Sunday's Six Nations opener against France after Luke Cowan-Dickie withdrew from Eddie Jones' squad.
Exeter hooker Cowan-Dickie pulled out of the group for "family reasons", team officials confirmed, with Saracens' Jack Singleton called up to take his place.
England have been training in Portugal's Algarve region ahead of their campaign.
With Cowan-Dickie unavailable, Saracens' Jamie George and uncapped Bath star Tom Dunn will contest the number two jersey, with Singleton in as cover.
George started in England's last match, the Rugby World Cup final defeat to South Africa in November.
