Marc Marquez has been denied the chanꦫce of fighting for a third MotoGP win in a row af﷽ter withdrawing from this weekend's Portimao return due to a training accident.

This time it is not the troublesome rigꦬht arm or shoulder that has kept him on the sidelines but a 'slight' concussion, sustained on an off-road bike, from which he is still feeling 'unwell' several days later.

"This p﷽ast Saturday Marc Marquez, while preparing for the Algarve Grand Prix with one of his standard off-road training sessions, suffered a fall that caused൩ a slight head concussion," said a Repsol Honda statement.

"After a few days of rest at home and seeing tha🌳t 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 comin🍸g wee𝔍kend Marquez will not contest the Algarve Grand Prix."

Marquez had been hoping to use this weekend's event to gauge the improvement in his right arm and shoudler, having made his comebac👍k from last season's injury complications at the earlier April round, when he finished in seventh place, 13s from victory.

After a series of DNFs in the run-up to the summer break, the eight-time world champion took an emotional win at the Sachsenring before returning to the top step in the last two races at🔯 COTA and Misano.

That put Marque🥀z in contention for fourth place in the world championship standings, despite missing both Qatar seas💦on-openers.

Marquez will now aim to be back on tꦡrack for next weekend's Valencia season finale.

Repsol Honda is yet to confirm if test ri༒der Stefan Br𓆏adl will replace Marquez, alongside Pol Espargaro (who finished second to the #93 in Misano) this weekend.
