Joel Tomkins, Elliot Daly and Will Fraser have been called into the England squad as injury cover ahead of Saturday's Six Nations match against France at Twickenham.
The trio have been in action for the Saxons recently and have now been promoted to the senior squad, who are chasing a Grand Slam after victories over Scotland and Ireland in their opening two matches.
Wasps centre Elliot Daly will provide training cover for Ben Foden, who is on a post-match recovery programme after ankle trouble.
And back row man Fraser of Saracens has been called up because number eight Ben Morgan is continuing his rehabilitation after an ankle injury.
Fraser's Saracens team mate Tomkins is an injury replacement for centre Jonathan Joseph, who is to remain with London Irish and have a foot injury treated.
Tomkins switched to rugby union towards the end of 2011 after a successful career in rugby league with Wigan, winning the Grand Final in 2010 and the Challenge Cup in 2011.
