Reigning
MotoGP champion
Casey Stoner is returning to action after missing three rounds due to ankle injuries.
Stoner's RCV stopped on track after just a few turns of his first run, forcing a switch to his spare bike.
Yamaha test rider Katsuyuki Nakasuga has been granted a wild-card entry for his home round, while Roberto Rolfo is replacing Mattia Pasini at Speed Master for the rest of the year.
