Cal Crutchlow had a goal to fit MotoGP tests in February 2019, admitting he originally hoped to run this weekend despite his injury to the required 12 months of civilian recovery.
The Honda LCR leader broke his right wrist in an accident on Friday afternoon for the Australian Grand Prix on Phillip Island last month.
He had an initial operation to stabilize the injury, but the full operation had to wait until the strain was reduced.
Although it was immediately clear that the injury was likely to end the 2018 season, Crutchlow said he initially hoped to return to the Valencia weekend finale this weekend and the next tests.
"The injury I have can recover for up to 12 months, although as a typical motorcyclist I thought I would return to the Valencia GP, unfortunately this is not the case," he said.
"I can not put weight on my wrist for six weeks, but I continue to recover and have physiotherapy.
"This week I will begin to try and go again and I'm looking forward to preparing for Sepang [testing] in February 2019. "
Honda test driver Stefan Bradl will replace Crutchlow in Valencia again.
Crutchlow had to spend 12 days at a hospital in Melbourne after an accident, while LCR manager Lucio Cecchinello stayed with him until he traveled to the next Malaysian GP.
"I had excellent surgeons in Matthias Russ and Dr Evans who initially put the external fixer on their feet until relief came and they could work, which was six days later," added Crutchlow.
"The collapse resulted in the break-up of the pylon of my bone of tibia, fibia and tusks." The operation was completed in three and a half hours and, together with the reconstruction of the artificial bone, two metal plates and eight screws were inserted. "
Before his accident, Crutchlow was fifth in the championship and a leading non-factory team driver.
It's still the seventh in the table, and the new driver who does not work best, Johann Zarco of Tech3 Yamaha is just one point ahead of him.
MotoGP has these two post-season tests this year – in Valencia after this GP and in Jerez a week later.
Sepang 2019 tests Crutchlow aims to start from February 3rd to 3rd next year.
