The situation is further complicated after Wasps coach Tony Hanks admitted Cipriani had "played through the pain barrier" in Saturday's Guinness Premiership defeat to Gloucester.
Hanks said: "Danny's problem was his ankle that he injured last year. There are times when it just becomes really sore. He played through quite a bit of pain."
Gloucester playmaker Olly Barkley would be in line for a return should Flood and Cipriani fail to convince Johnson they are fit to face Frank Hadden's team.
England suffered a humiliating defeat at Murrayfield last year the week after pulling off a shock victory over France in Paris and No8 Nick Easter is determined not to let the euphoria of yesterday's win affect preparation.
He said: "Scotland are a good side. We went up there a bit over confident last year and they shut us out. We know exactly what they are capable of."
France, meanwhile, today named an unchanged squad to face Italy despite their mauling in England.
Head coach Marc Lievremont said: "We thought this squad could win at Twickenham and we still think they can win in Rome."
