Fernando Alonso says he is "giving everything" to return to the cockpit of his McLaren Formula One car in the Malaysian Grand Prix.
The Spanish driver is sitting out the Melbourne opener following recommendations form his doctors after the concussion he suffered in his crash during testing at Barcelona.
Kevin Magnussen will race the second McLaren alongside Jenson Button.
Alonso admitted it is hard to miss the first grand prix of the year, but said he is already pushing hard to be back at Sepang.
"Of course, I'm very disappointed not to be joining Jenson in Melbourne in the McLaren-Honda garage, but I understand the recommendations of the doctors and I'm already back in training and preparing for my first race in the MP4-30," said Alonso in a team preview.
"I would like to thank everybody for their kind wishes and support and I'll be giving everything to be back in the cockpit for Malaysia.
"I wish Kevin all the best for this weekend in Australia, and I know the car is in his safe hands!
"Even though we faced a lot of challenges in the tests, I am very encouraged by the feeling I got from the car, and I'm looking forward to going through all of the data from this weekend with the team to continue our push for development and improve our performance."
