"The good news is, that there is no bone fracture, it is healing faster every day, but we still wait for the final confirmation that Miguel can start the race, although we are quite optimistic."

Team-mate Hafizh Syahrin will be competing in front of his home fans for the final time before switching back to Moto2 in 2020.

“I’m very happy to arrive at my home GP. It’s a special weekend for me and I will do my best," said Syahrin. "We know, we are struggling this year and Sepang is the second last Grand Prix race before I go back to Moto2.

"It won’t be easy, but I will give everything I have, similar to last year," added the Malaysian, who charged from 23rd to 10th in front of his home fans last season. "I want to do this for my fans, my family and for my team, that always supports me and believes in me.

"We will see what we can do, I just want to enjoy to ride there. Australia was good, but we learned that we need to improve in the beginning of the race. I will keep my motivation high and I can’t wait to enjoy this weekend with everybody.”

Poncharal, who signed Syahrin for his Yamaha team in 2018 after Jonas Folger's withdraw, then kept the Malaysian for the switch to KTM this year, added:

“For our team this is a significant and important race with Hafizh doing his home GP. Apparently, the circuit is sold out and there will be many, many spectators in the audience cheering for him.

"So clearly, after the good performance he showed in Australia, it will be interesting to see how he starts the Malaysian round. We have had quite a lot of intensive testing here in the winter, so for sure we have data, which was not the case on most of the circuits we were visiting this year."

After a peak finish of ninth on a Yamaha, Syahrin has a best race result of 13th so far this season. He will join the Angel Nieto squad in Moto2 next year, when rookie Iker Lecuona will take Syahrin's place at Tech3.
