Fernando Alonso must overcome three hurdles if he is going to be allowed to race in next weekend's Malaysian Grand Prix.
The Spaniard missed the season-opening Australian Grand Prix after suffering concussion in a crash during the second pre-season test in Barcelona last month. He sat out the race in Melbourne on doctors' advice, and having stepped up his preparations for a return with a simulator session last week, The Guardian reports he will now have to undergo a series of tests to determine whether he can drive at Sepang.
The first set of tests will take place today at the University of Cambridge in the UK, where three FIA-appointed specialists will examine Alonso to see if they deem him fit to attempt to race in Malaysia.
If Alonso passes Sunday's tests, he will then have to be checked during the race weekend, first with the chief medical officer at the Sepang International Circuit before a final test with FIA medical delegate Jean-Charles Piette.
The final test with Piette is known as the FIA's 'impact test', and will see Alonso judged against his own scores from a previous test which analyses reaction time and a number of cognitive skills.
