Scottish rider John McPhee has left Australia, six weeks after being injured in a Moto3 crash at Phillip Island.
The Brno winner crashed and was then involved in a pile-up early in the Phillip Island race on October 23, sustaining a broken thumb and a concussion.
However doctors also detected an accumulation of air between a lung and his chest wall, which ruled out flying home, or to any of the final two races of the season at Sepang or Valencia.
McPhee was discharged from hospital in late-October and resumed training in mid-November.
The 22-year-old had pins removed from his left thumb last week, and flew out of Melbourne on Monday.
He described his 2016 as a "rollercoaster season", having won taken a breakthrough victory in the rain at Brno but finishing 22nd in the championship on a Peugeot-badged Mahindra.
McPhee will stay in Moto3 next year for a fourth full season in the class, but will switch back to a Honda.
