Although Alex de Angelis will be back in the MotoGP paddock in Valencia he won't be racing with Broc Parkes filling in at Ioda Racing.
The 33-year-old Parkes, whose best race result in MotoGP was a P11, last raced in the premier class in 2014.
Parting ways with Paul Bird Motorsport at the end of the season, he switched to British Superbike Championship before trying his hand at endurance racing.
Parkes, though, is now set to return to the MotoGP in a one-off appearance replacing de Angelis for the Valencia season finale.
De Angelis continues to return from the serious rib, spine and lung injuries that he suffered during a crash at Motegi last month.
