Bastianini made a return to on-track action with a Panigale V4S in the hope of being cleared for a return to MotoGP, however, after undergoing a medical check the Italian has again been ruled out. That means Ducati test rider Pirro steps in for his first appearance of the season.

Like Pirro, Honda’s official test rider Bradl will be making his first appearance of the year after Marquez was ruled out due to the right hand injury he suffered in Portimao. After missing the Argentine Grand Prix last time out due to a nasty crash in the Sprint, Mir is set for a return.
