The double world champion missed the opening round of the season in Australia following a crash in his McLaren in the second pre-season test in Barcelona in which he sustained concussion . Alonso has since undergone numerous tests and examinations to ensure he is fit to step back into the cockpit of his car , with a final medical assessment by the FIA due to be conducted on Thursday at the Sepang International Circuit . Fernando Alonso has declared himself fit after recovering from concussion for the Malaysian Grand Prix . Given the heat and high humidity in Malaysia the FIA will also be eager to satisfy itself Alonso will be able to cope with the conditions . The Spaniard is adamant he is fine as he said : ' I 've been working hard on my fitness and I feel good and ready to go this weekend . 'The heat in Malaysia is always very tough for the drivers , but I 've been focusing on this in my training and I 'm definitely prepared for all of the weather conditions we can face in Sepang . ' The Spaniard suffered the concussion after being involved in a serious crash during testing . Alonso was airlifted to hospital and did n't take part in the opening race of the Formula One season in Australia .

Aware of the difficulties to come , Alonso added : ' I watched the weekend in Australia very closely and I was in touch with the team from the moment they arrived . After leaving Ferrari to sign with McLaren-Honda , the Spaniard will be hoping to get the all clear to race . 'It 's clear we have a lot of work ahead of us , but Jenson 's result in Melbourne was encouraging from the point of view of reliability and data collection , which are extremely important . 'The weekend will still be tough , but I 'm looking forward to getting into the car for the first time in a grand prix and getting back to racing . ' I 've spent some time in the simulator back at the factory , and my focus will be on continuing the development of our package with my engineers , and working on our balance and race set-up . 'There 's a lot of potential in the car and we will keep pushing every race until we see results . 'Although we are a long way from the front , everyone in McLaren-Honda is working hard to develop the package and keep building momentum with each race . '
