England rugby union head coach Stuart Lancaster has added Exeter Chiefs scrum-half Haydn Thomas, along with Sale Sharks lock Kearnan Myall, to his squad for this Sunday's match against the Barbarians at Twickenham (1pm).
Thomas and Myall will complete a 25-man squad preparing to take on an experienced Barbarians line-up. Thomas, 30, is in contention for a first appearance in a senior England shirt, while Myall, 26, has featured for England Saxons since 2009.
Lancaster said: "This week it's good to have Haydn and Kearnan involved in the senior England environment ahead of what should be a great game against a very strong Barbarians team. They have both played well recently and deserve this opportunity."
Exeter Chiefs flanker Tom Johnson is also in the England squad. England will name their side for Sunday's match against the Barbarians, whose squad includes Exeter Chiefs and Australia lock Dean Mumm, on Friday at 11am.
