Fernando Alonso and Valtteri Bottas have been declared fit to return to the cockpit in this weekend's Malaysian Grand Prix.
The Spaniard had already been given the green light prior to travelling to Malaysia this week by a panel of FIA-nominated doctors at Cambridge university.
But he also had to satisfy FIA medical delegate Jean-Charles Piette on Thursday, as well as Sepang's resident doctor.
The FIA announced that Alonso duly passed all the "mandatory fitness tests" on Thursday.
Williams driver Bottas, who suffered a back injury in Australia, was also cleared to race this weekend.
