The England prop Andrew Sheridan has been ruled out of Sunday's Six Nations rugby clash with Italy after suffering a back injury.
Powerful loosehead Sheridan will be replaced in England's starting line-up by London Irish's Alex Corbisiero, who will be making his Test debut in the front row.
Corbisiero -- who was not in England's 22-man squad for the Italy game -- is promoted ahead of David Wilson, who remains on the bench.
Johnson said he had no qualms about pitting Corbisiero against Italy's powerful scrum, where he will be packing down against Leicester's Martin Castrogiovanni.
