Formula One doctor Ian Roberts and medical car driver Alan van der Merwe have tested positive for COVID-19 and will be replaced for this weekend's Turkish Grand Prix, the sport said on Thursday.
Formula One and the governing FIA said the pair had not travelled to Istanbul and a team from the all-electric Formula E championship was standing in for them.
Formula E's Safety Car driver Bruno Correia will drive the medical car, while the Formula E medical delegate Bruno Franceschini will replace Roberts.
South African van der Merwe and Briton Roberts helped former Haas driver Romain Grosjean make a 'miracle' escape from a fiery Bahrain Grand Prix crash last year and were hailed as heroes after the drama.
