If Rossi decides not to participate, current WorldSBK pilot Michael van der Mark, who claimed a podium at Portimao World Superbike this past weekend, will substitute on the YZR-M1 prototype at Aragon.
The news of his August 31 crash arrived after Rossi made history at Silverstone. There, Rossi became the only rider in GP history to achieve 300 premier-class starts. Rossi finished fourth at the British Grand Prix, and was forced to miss his home race at Misano.
So far this season Rossi achieved four podiums, including a win at Assen. With five rounds remaining, VR46 is fourth in points with 157, 42 behind the men who are tied for first, Repsol Honda’s Marc Marquez, who won at Misano, and Ducati Team’s Andrea Dovizioso.
Rossi also suffered another slight setback earlier this season during a motocross-training crash ahead of Mugello. He complained of pain in his stomach and chest, but raced anyway, and finished fourth at Mugello.
Rossi’s last fracture was during the 2010 Italian Grand Prix at Mugello; he missed six weeks of racing that year. That year he finished third overall.
