Injury doubts over David Wilson and Kyle Eastmond have prompted England coach Stuart Lancaster to call up Henry Slade and Henry Thomas.
England have called up Henry Slade and Henry Thomas as injury cover for David Wilson and Kyle Eastmond ahead of Friday's Six Nations curtain-raiser against Wales.
Coach Stuart Lancaster has been plagued by injuries in the build-up to the fixture, with Bath duo Wilson (neck) and Eastmond (shoulder) among a host of players to pick up problems on club duty last weekend.
The final round of European pool fixtures spelt the end of Owen Farrell's involvement in the tournament, with the Saracens fly-half sustaining a knee ligament strain, while Brad Barritt, Geoff Parling (both knee) and Tom Wood (ankle) are all fighting to be fit.
However, Lancaster is pleased to be able to call on Bath prop Thomas and uncapped Exeter Chiefs back Slade, who contributed 13 points as England Saxons defeated Ireland Wolfhounds 18-9 on Friday.
"We are hoping that David's injury will settle down but we need to consider our options at tighthead over the next few days and Henry [Thomas]'s form deserves consideration," he said.
"Kyle's scan showed that he does not need surgery but he is not back training so we have the option to bring Henry [Slade] in on the back of a good performance out in Cork.
"Tom also does not require an operation, so he is being treated in camp for his ankle injury and is making good progress. He should come into consideration over the next week or so."
Lancaster also revealed that Sam Burgess, who has also been playing with the Saxons, will now spend time with the senior squad to aid his transition from rugby league to union.
"Sam will just come into camp for two days to further his rugby experience before returning to Bath on Monday evening to get more game time with the club over the next few weeks," Lancaster added.
"He is still learning the game and this is an opportunity to help his development."
England are also without Joe Launchbury (back) and Ben Morgan (broken leg).
