Martin fractured his right wrist during a sprint race battle with title rival Marc Marquez in Australia and was ruled out of the main race, which was later cancelled due to heavy rain and poor visibility.
Martin is 10 points adrift of Ducati's Marquez in the MotoGP standings with four rounds remaining.
"Martin will be out on track in the opening stint of a crucial grand prix in the ever-changing 2026 title race," Aprilia said in a statement.
"MotoGP’s medical team will review Martin again after FP1 (Free Practice 1)."
Trackhouse Racing's Raul Fernandez was declared fit after recovering from a finger fracture that forced him to miss the Australia round, while Honda riders Luca Marini and Joan Mir are also set to return after overcoming illness.
