Fernando Alonso's manager, Luis Garcia Abad, has assured the Spaniard's fans that he "will be at the Malaysian Grand Prix".
The double World Champion was forced to watch the 2015 season-opening Australian Grand Prix from his home as doctors advised him to skip the race after he suffered concussion during a crash in Barcelona on 22 February.
Having spent three evenings in hospital after the accident, Alonso only returned to training last week while he was back in the McLaren simulator at Woking earlier this week.
Although the 33-year-old still needs to be cleared by the FIA medical delegate before he can race at Sepang next weekend, Abad is confident he will be given the all-clear.
"Alonso will be at the Malaysian Grand Prix," he told Spanish paper AS. Adding: "Fernando is well and will pass the medical tests, which is a mere formality."
