Marussia driver Timo Glock wasruled out of the European Grand Prix with an intestinal infection.
Glock was taken severely ill on Saturday after complaining of feeling unwell on Thursday, forcing him out of qualifying at the Valencia Street Circuit.
After a medical examination and waiting to assess the situation following rest overnight, the decision was taken to pull the German out of the race.
A team statement read: "Further to the medical problem which prevented Timo from participating in yesterday's qualifying session, the Marussia F1 Team can confirm that Timo is unable to compete in today's race.
"Timo received medical guidance yesterday afternoon and his symptoms suggest he is suffering from an intestinal infection.
"He has been advised that it would be unwise for him to race given the severity of the complaint and that he should focus instead on recuperating.
"Timo spent the evening resting at his hotel in Valencia and is in good spirits. He will return home later today."
