Mercedes boss Brawn too sick to attend Spanish GP 10 May, 2012 Ross Brawn with Nico Rosberg and Michael Schumacher May 10 (Reuters) Mercedes team principal Ross Brawn will miss Sunday’s Spanish Grand Prix on doctors’ advice, the Formula One team said on Thursday. Technical director Bob Bell will take charge, with team chief executive Nick Fry and Mercedes motorsport vice-president Norbert Haug also at the Circuit de Catalunya. A team spokeswoman said Brawn, whose team won last month’s Chinese Grand Prix with Germany’s Nico Rosberg for their first success as a works outfit since 1955, was expected to be back for Monaco later this month. The team gave no details about the Briton’s illness. Brawn won multiple world championships with Benetton and Ferrari as a technical director and then led his own Brawn team to the 2009 title, created from what remained after Honda’s withdrawal drom the sport. Mercedes Benz then bought the team and re-named it Mercedes GP. Sunday’s Spanish race is the fifth round of the season, and the first of the European leg of the season.
