Michael Schumacher will make a shock return to Formula 1 to replace injured Ferrari driver Felipe Massa.
The seven-time world champion retired at the end of 2006 but will drive at the European Grand Prix on 23 August.
Ferrari said the 40-year-old will stand in for as long as Massa is sidelined by the serious head injuries he sustained in the Hungarian Grand Prix last week.
"For team loyalty reasons I can't ignore this unfortunate situation," said the former Ferrari driver.
His spokesman Sabine Kehm had told the BBC on Tuesday that although Schumacher - who was working as an advisor for Ferrari - was not willing to make a full-time return to F1, he would not rule out standing in for Massa.
