Northampton prop Paul Doran-Jones has joined the England squad preparing for next week's Six Nations clash with Wales at Twickenham.
The 26-year-old tighthead is a temporary replacement for Bath's David Wilson, who will stay with his club to recover from a jaw injury.
Doran-Jones is among 31 players training until Thursday of this week at England's Bagshot base in Surrey, when coach Stuart Lancaster will decide which players to release from the squad.
England and Wales are the only two unbeaten sides in the competition, having both collected a maximum four points from their first two Six Nations games. The Reds top the table at the moment because of a narrowly superior points difference.
