Dutch TT winner Jack Miller has been passed fit to contest this weekend's British Grand Prix, meaning Nicky Hayden will not return to MotoGP as a stand in.
The Marc VDS rider sustained hairline fractures to his T6 vertebra and right wrist in a warm-up accident at last month's Austrian Grand Prix at the Red Bull Ring.
Although he had been given medical clearance to return for the Czech GP at Brno a week later, the decision was made to rest him to ensure he made a complete recovery.
But further tests were required at Silverstone today to ensure Miller was fit enough to return.
"After a medical assessment that showed significant improvement to the back injury, Jack Miller will ride in the British GP," said a team statement.
Hayden, who left MotoGP at the end of 2015 to race in the World Superbike Championship with Honda, was the likely stand-in had Miller not been fit.
