Timo Glock insists his appendicitis mere weeks before the start of the 2011 season has not overly affected his preparation.
"The operation has put me back two to three weeks," he told the DPA news agency, "but as I was previously training hard, it won't be much of a problem."
It was faintly hoped the German would be well enough to drive in Barcelona, but Virgin has confirmed that teammate Jerome d'Ambrosio will do all the running this week.
Germany's Bild newspaper, however, said Glock will be at the Circuit de Catalunya on Thursday, but will do no driving.
"Timo's feedback would obviously have been extremely beneficial here, but it's more important that having recovered well from his operation we don't take any risks as we need him to be fighting fit for the opening race," said team boss John Booth.
