Ineos Grenadiers sports director Oli Cookson has been fined £4,700 and issued a yellow card after hitting a spectator while driving behind the breakaway during today’s stage of the Tour de France, won by the British team’s Dutch rider Thymen Arensman.

Cookson, a longstanding staff member at the squad and the son of former UCI president Brian Cookson, was driving the team car behind Ineos duo Arensman and Carlos Rodríguez, who had attacked as part of a small escape group during stage 14’s 182km Pyrenean epic.

With around 32km to go, a few hundred metres from the summit of the Col de Peyresourde, the third of the stage’s four major climbs, footage emerged of the driver of the Ineos team car striking a spectator, who was standing in the road.

In the footage, the spectator, wearing a green coat and part of a crowd of fans standing on the left-hand side of the road near the top of the Peyresourde, can be seen filming the breakaway with her phone when she was struck by Cookson’s car.

She briefly landed on the car’s bonnet before clattering to the ground, the driver immediately stopping the car following the impact. The condition of the woman is not yet clear, though Tour de France organisers ASO have been approached for comment.

Following today’s stage, which Arensman won solo Superbagnères, a minute clear of yellow jersey Tadej Pogačar, the official communique issued by the Tour’s commissaires revealed that Cookson has been fined and yellow carded.

Though the Tour did not explicitly state the incident as the reason for the jury’s decision, the communique said Cookson was reprimanded for “incorrect behaviour endangering spectators”, citing article 1.12.007-8.2.2 of the UCI rules.

The British sports director was fined 5,000CHF (around £4,700) for his role in the crash, and issued a yellow card.

Under the UCI’s new warning system, introduced earlier this year, this means that if Cookson receives another yellow before the Tour is finished, he will be disqualified from the race and handed a seven-day suspension.
