After a nightmare weekend of European Champions Cup rugby for Stuart Lancaster, the England coach has called up Tom Croft and Christian Day.
Tom Croft and Christian Day have been called into the England squad for the Six Nations opener against Wales following a costly weekend of European Champions Cup rugby.
Leicester Tigers flanker Croft - a veteran of two British and Irish Lions tours - and uncapped Northampton Saints lock Day joined up with the team on Monday after a host of players picked up knocks on club duty.
The duo are seen as replacements for Geoff Parling (knee) and Tom Wood (ankle), who are awaiting full assessment from the England medical team.
Meanwhile, backline trio Brad Barritt (knee), Kyle Eastmond (shoulder) and Owen Farrell (knee) are also being assessed, and Luther Burrell will undergo the graduated return to play protocol after sustaining a concussion against Racing Metro on Saturday.
The Saints wing could, though, return to training on Friday.
"The players will be fully assessed once they get into camp [on Monday] and it's too early to give any definitive news on their status," said coach Stuart Lancaster. "Tom's ankle and Owen's knee has been scanned.
"Owen will see a specialist and we will be able to provide an update on him and the other injured players [on Tuesday], along with any other potential additions to the squad."
Bath's Carl Fearns and James Gaskell of Wasps will replace Croft and Day in the England Saxons squad.
