Formula One: Alonso cleared to compete in this weekend's Malaysian Grand Prix

SEPANG, Malaysia (Reuters) - Fernando Alonso passed a final medical examination on Thursday and will be able to participate in the Malaysian Grand Prix this weekend after the Spaniard missed the season-opener in Australia due to concussion.

The double world champion was sidelined following a winter-testing crash in Barcelona last month after leaving Ferrari for McLaren at the end of last season.

Alonso flew to Malaysia after coming through tests by three doctors at Cambridge University on Sunday and then passed the official examination by the governing body's medical delegate and the Sepang Circuit's chief medical officer.

Considered one of the most skilful drivers in Formula One, he will need to be at his very best to have any chance of picking up points on his return to racing for a team who fared poorly in Australia.

Struggling for pace and reliability with the new Honda engine, team-mate Jenson Button crawled around Albert Park to cross the line last of the 11 finishers.
