The returning pair will continue rehabilitating their respective injuries alongside a 36-man group, the Rugby Football Union has announced.
Exeter wing Immanuel Feyi-Waboso, who scored a try as a replacement in Saturday’s 30-21 Calcutta Cup loss to Scotland, will be absent as he has a medical exam at Exeter University which must be completed face to face.
England return to action on Saturday, 9 March when Grand Slam-chasing Ireland visit Twickenham.
