Adam Norrodin will miss what should have been his final Moto3 grand prix appearance, due to injury.
The Malaysian charged from the pit lane to a high of seventh before falling on the penultimate lap of his home event last weekend.
Norrodin, who dislocated his shoulder at Motegi, was in pain on his return to the pits and will now undergo surgery to cure the shoulder instability and discomfort at the Kuala Lumpur Sports Medical Center.
In approximately six weeks time, a second surgery will be needed to repair an injury sustained to his left knee in July.
Norrodin, a grand prix rider since 2016, has lost his Sepang seat for next year but will continue to be backed by SIC for a move to the Spanish Moto2 Championship.
“It’s been a very difficult decision not to race in Valencia, but in the end I had to think about my future and the long term effect of delaying the operation," Norrodin said. "I’m really sad to be ending my Moto3 career this way; I’ve really enjoyed my time with the team and I wanted to see them one last time and to finish on a high.
"After my race in Malaysia, I was feeling so motivated to go to Valencia, but in the end I had to think about my future, to make sure that I am physically prepared for it.
"Now my focus is on next year and competing in Moto2, in the Spanish Championship, so I want to be 100% fit and ready to start this new chapter in 2019.
"I wish all the best to my team for the Valencia race – I will be watching and supporting them from home. I want to say thank you to them all for their support over the years and I look forward to seeing them all again soon.”
