But it removes another option from the back-row alternatives, with Tom Croft also unlikely to play any part until the middle of the campaign as he feels his way back from a neck injury.
"Tom Johnson is probably facing a three-month recovery time. For him it is a tough blow," said head coach Stuart Lancaster, who had already brought uncapped Worcester flanker Matt Kvesic into the squad as cover.
England's biggest concern is over Corbisiero, who has not played since
the victory over New Zealand
on 1 December. He was due to have his troublesome knee "cleaned out" on Wednesday.
England's casualty list
Calum Clark (flanker) - out of whole Six Nations
Tom Johnson (flanker) - out of whole Six Nations
Alex Corbisiero (prop) - will miss at least first two games
Freddie Burns (fly-half) - will miss first two games
Manu Tuilagi (centre) - doubt for Scotland game
"His knee hasn't settled down," Lancaster explained. "It keeps swelling after small amounts of exercise. There is a loose body in there. He has gone in for a scope today to get that loose body taken out and hopefully that will settle down for him.
"We will get him rehabbed and back playing for London Irish. That will take him out of the first two games as a minimum."
In Corbisiero's absence, Harlequins loose-head Joe Marler is likely to regain the starting role he relinquished to the London Irish player in the autumn, with Saracens' Mako Vunipola the other alternative in the elite squad.
Burns, who made such an impressive debut as a replacement against the All Blacks, will also have to put
his Six Nations ambitions
on hold for the time being, leaving the fly-half spot a straight choice between Owen Farrell and Toby Flood.
"Freddie has had a scan on his MCL," Lancaster added. "It is a grade two injury so not as bad as first feared, but it will keep him out for two or three weeks. We will try to get him back as soon as we can."
