Abraham suffered a badly dislocated toe in a fall at the Catalan Grand Prix, and was forced to sit out last week's Dutch TT. It has now been confirmed that he will not be fit to race in Germany, and his spot at AB Motoracing will be filled by Aoyama.
It is not the first time this season that the Honda test rider has been promoted to the grid, with the Japanese rider having replaced Dani Pedrosa for three rounds while the Spaniard was recovering from arm pump surgery.
During that time, Aoyama was only able to register a best finish of 11th, a result which came in Austin. He failed to finish in Argentina and Spain.
