Corbisiero to face Scotland
England manager Martin Johnson has made one change for Sunday's Calcutta Cup game against Scotland, with Alex Corbisiero replacing the injured Andrew Sheridan at loose-head prop.
Corbisiero will win his third cap after Sheridan tore his calf in England's 17-9 victory over France and was ruled out of the remainder of the RBS 6 Nations Championship.
Toby Flood has recovered from the Achilles injury that forced him off against France to continue at fly-half in a settled starting team.
The only position in which Johnson has had to make changes all tournament is at loose-head prop and they have all been forced upon him by injuries.
Corbisiero made an impressive debut against the feared Italian front row when Sheridan was pulled out on the eve of the game with a back injury.
Johnson has made two alterations to his bench for the Scotland clash.
Tom Croft returns to an England squad for the first time since fracturing his shoulder against South Africa in the final international of the autumn campaign.
The Leicester flanker has replaced Hendre Fourie among the replacements after proving his fitness in three appearances for the Tigers.
Gloucester prop Paul Doran-Jones has been promoted to fill Corbisiero's place on the bench with David Wilson still struggling with an ankle problem.
But Northampton lock Courtney Lawes will have to wait for his return to England action, with veteran lock Simon Shaw continuing to provide the second row cover.
Lawes declared himself fit for action after returning from knee ligament damage for Northampton and has been training with the squad.
England are unbeaten after three RBS 6 Nations fixtures for the first time since they last completed the Grand Slam, when Johnson was captain in 2003.
Johnson's men are red hot favourites to despatch the Scots, who have not won at Twickenham since 1983 and head into the game on the back of defeats to France, Wales and Ireland.
