London - England coach Stuart Lancaster added nine players to his squad on Sunday ahead of next month's Twickenham internationals against world champions New Zealand, South Africa, Samoa and 2015 World Cup pool rivals Australia.
Lancaster named his original 33-man squad on Wednesday but had the option of adding to the party after this weekend's round of European club matches.
The Exeter trio of Dave Ewers, Henry Slade and Thomas Waldrom came into the squad as injury cover for Wasps back-row James Haskell, Northampton centre Luther Burrell and Saracens back-row Billy Vunipola respectively.
Burrell left the field clutching his right hand in the 43rd minute of English champions Northampton's 34-6 European Rugby Champions Cup pool win at home to Welsh regional side Ospreys on Saturday.
Fellow centre Manu Tuilagi has already been ruled out of England's end-of-year Twickenham opener against the All Blacks on November 8 because of a groin problem.
Vunipola is recovering from concussion suffered in Saracens' European defeat by Munster on Friday, while Haskell is still getting over a viral infection.
Ben Foden (Northampton), Matt Kvesic (Gloucester), Anthony Watson (Bath) and Richard Wigglesworth (Saracens) will also train with the squad as cover for the players involved in Sunday's European games.
Meanwhile Henry Thomas (Bath) and Alex Waller (Northampton) have been added as cover for front-row forwards David Wilson and Joe Marler, who have calf and thigh injuries respectively.
Backrow forward Tom Wood has remained in Northampton with his wife pending the birth of their third child and will join the squad later this week.
"We always anticipated bringing in additional players following the European games, either to cover injuries or for training," Lancaster said in a Rugby Football Union statement issued Sunday.
"Luther will be assessed by a specialist over the next 48 hours and our medics are in close contact with Saints so we'll know more in a few days but it's great to be able to bring in Henry (Slade).
"Injuries are inevitable but we are excited about the group we have in camp. We are raring to go and looking forward to getting out on the training pitch tomorrow (Monday)," added Lancaster ahead of a set of matches that will act as a marker for World Cup hosts England less than a year out from the global showpiece event.
