Marc Marquez is expected to return at the Portuguese Grand Prix, but the MotoGP Medical Director has advised against it.

The MotoGP Medical Chief, Dr Angel Charte, has ruled out the chance of Marc Marquez being back on the grid before the Valencia Grand Prix.

On the opening lap at the Indonesian Grand Prix, Marquez suffered a fracture and ligament damage to his right shoulder in a collision with Marco Bezzecchi.

Originally, it was declared that Marquez did not need to undergo surgery, but it was then decided that the Spaniard would need to undergo surgery, and he underwent a successful operation.

The nine-time World Champion has been declared unfit for the Australian and Malaysian Grand Prix, and will be replaced by Michele Pirro at Phillip Island.

However, Dr Charte also believes that Marquez should not race at the Portuguese Grand Prix in the penultimate round of the 2025 MotoGP World Championship.

Speaking with DAZN on Thursday at the Australian Grand Prix, Dr Charte said Marquez's new injuries need to be 'treated with car'.

"Last week, during a check-up at the Clinica Ruber Internacional in Madrid, Dr Roger de Ona and his team decided that it [the injury] was unstable and, using their best judgement, decided to fix it much better," he said.

"Marc has already undergone surgery, was discharged after 24 hours and has begun a period of rest. When the doctor deems it appropriate, he will begin his recovery.

"[He is already ruled out for] Australia, Malaysia, and a return to Portugal will be quite complicated, I think, because it's an injury that can have lasting effects if it's not treated with care."
