Yuki Tsunoda allegedly impeded Valtteri Bottas in qualifying during a fast run. The AlphaTauri driver is due to appear before the stewards at 17:10 [local time] to explain the incident.
Tsunoda himself revealed in an interview with Sky Sports that the team had not informed him of the oncoming Bottas. Moreover, he states that he could not have gone anywhere at that point on the track.
The incident took place in Q1. In the end, both men even went through to Q3 and so a grid penalty seems a very severe punishment, but ultimately the verdict is up to the stewards at the Red Bull Ring.
