Hirakawa replaces Ocon for Mexico City Grand Prix

Esteban Ocon has been replaced at Haas by the team's Japanese reserve driver Ryo Hirakawa for the remainder of the Mexico City Grand Prix weekend.

Ocon, who is leaving the team at the end of the year, drove in Friday practice but the team released a statement on Saturday saying Hirakawa would drive instead of the Frenchman on Saturday and Sunday.

The team gave no further details about the reasons behind the decision, although a spokesperson at Haas said it was not because the Frenchman was ill.

The move comes after Ocon had a dispute with his race engineer Laura Mueller during second practice on Friday about tyre strategy.
