The six-time MotoGP champion suffered the accident last Saturday while preparing for the penultimate round of the season in Portimao, where he would have been going in search of a third successive win.

Marquez was still feeling unwell on Tuesday following a few days of rest at home and the Repsol Honda rider will not race at the Algarve Motorsports Park as a precautionary measure after a medical check-up.

The Spaniard’s team said in a statement: “This past Saturday Marc Marquez, while preparing for the Algarve Grand Prix with one of his standard off-road training sessions, suffered a fall that caused a slight head concussion.

“After a few days of rest at home and seeing that he was still unwell, today Marquez has been assessed by doctors in a medical check-up to evaluate his current status.

“As a precautionary measure, this coming weekend Marquez will not contest the Algarve Grand Prix.”

Marquez missed the start of the season as he continued to recover from a serious arm injury.

He returned at the Portuguese Grand Prix in April and is sixth in the standings with 142 points following back-to-back victories in Austin and at the Emilia Romagna Grand Prix, when Fabio Quartararo sealed the title.
