Bit of a logistical nightmare, eliminations this week and next week would mean only 2 in the final?

Given how last minute this is, and as the producers have already used up their safety net after Amanda's withdrawal, it can be inferred from the BBC News article that they are at least looking at possibly skipping this week's elimination 

A spokesperson said: "Unfortunately Nigel has sustained an injury which means he is unable to perform and has had to withdraw from Strictly".
It is not clear whether an elimination will still go ahead this week.
The remaining celebrities are actress Ellie Leach, tennis star Annabel Croft, theatre and TV star Layton Williams and EastEnders actor Bobby Brazier.
Asked what would happen this week, a BBC spokesperson said: "It's a live situation and the logistical details will be revealed on the show this evening."
Initial reports suggested Harman had suffered a leg injury, but it was later clarified by the BBC that it was a rib injury.
