Danny Cipriani and Nick Easter are set to be included in an England training squad for the Six Nations opener against Wales.
Head coach Stuart Lancaster will name a party of approximately 34 players at 11:00 GMT on Wednesday ahead of a camp next week.
Sale's Cipriani is understood to be one of four fly-halves in the group, along with George Ford, Owen Farrell and Stephen Myler.
England will play Wales on 6 February.
Barring injury, Ford and Farrell are likely to be the two stand-offs involved against Wales in Cardiff, but both Myler and Cipriani have a chance to impress in training.
Meanwhile the England management are set include 36-year-old number eight Easter, who won the last of his 47 caps in the 2011 World Cup.
Easter has been in outstanding form for his club Harlequins and earlier this month told BBC 5 live that he was "desperate" to play for England again and was "100%" confident he could still perform at international level.

A host of British and Irish Lions who missed the Autumn internationals through injury are set for recalls, with forwards Alex Corbisiero, Mako Vunipola, Tom Youngs and Geoff Parling among those expected to be included - although centre Manu Tuilagi is likely to miss the whole championship because of his groin injury.
Jonathan Joseph will be rewarded for a string of impressive performances for Bath with a place in the senior training squad, while his club team-mate Sam Burgess will be named in the England Saxons squad for the game against the Irish Wolfhounds in Cork on 30 January.
Gloucester number eight Ben Morgan is definitely out of the Six Nations with a leg injury, while Northampton Saints full-back Ben Foden misses out for the second successive year because of a knee injury.
On the Monday or Tuesday before the Wales game, the training squad will be cut to the matchday 23, with the rest released back to their clubs.
