WORLD Cup winners Iain Balshaw, below, and Lewis Moody are racing against time to be fit for England's RBS 6 Nations Championship opener against Scotland at Twickenham on Saturday.
Gloucester full-back Balshaw (groin) and Leicester flanker Moody (shoulder) both suffered injuries during training at Bath.
England have immediately summoned Balshaw's uncapped Gloucester colleague Olly Morgan and Wasps forward Tom Rees, another Test rookie, from the Saxons squad commitments in Exeter, where they were preparing to face Italy A tomorrow night.
Balshaw has seen his England career regularly stalled by injury setbacks, and if the 27-year-old once again finds himself out of luck, head coach Brian Ashton must decide whether to hand Morgan an international debut or rework his existing resources.
The latter option might mean a switch of positions from wing duties for either Josh Lewsey or Jason Robinson, while Mathew Tait could also have a role in the back three.
Rees would be a straight swap for Moody on the replacements' bench, with definitive medical bulletins expected before the squad head to London later today.
Hooker George Chuter, meanwhile, has welcomed the selection of Robinson, Jonny Wilkinson and Andy Farrell in a team largely unrecognisable from the world champions' last game, a 25-14 defeat against South Africa 10 weeks ago.
Wilkinson makes his first England start for more than three years, while Robinson will end a 16-month spell in Test retirement and ex-Great Britain rugby league captain Farrell is handed the number 12 shirt after less than a dozen union appearances.
Chuter said: "You cannot buy the experience of people like Jonny and Andy. Their know-how is vital."
