Alex Rins broke his right leg in an accident in Mugello in June and underwent surgery.
With the summer break being lasting for five weeks, many thought Rins would return at Silverstone, but did not show up after it was determined that he was still recovering.
The expected turnaround did not happen in Austria either, and Rins was still walking on crutches.
A recent statement from LCR Honda confirmed that Rins would not be able to race for the remainder of the season.
Rins will be replaced by Honda WSBK driver Iker Lecuona. Lecuona has been in the LCR Honda seat since Assen.
Rins brought Honda their only victory this year, but was dissatisfied with the team and felt he wasn't getting enough support.
After all this, the parties mutually agreed to part ways early, and Rins agreed with Yamaha.
Johann Zarco, who left Pramac Ducati, will fill Rins' seat. It is still unclear whether Takaaki Nakagami will remain in the team.
There is talk of Nakagami being replaced by Lecuona, but it seems more likely that he will continue with Honda at WSBK.
