Damage from a loose drain cover in the pit-lane has prevented Valtteri Bottas from participating in final free practice for the European Grand Prix in Baku.
The Finn, a podium winner last time out, was coming back into the pit-lane after an installation lap when he kicked up a drain grate with his front wheel, which ricocheted into the sidepod of the Williams FW38.
Bouncing off the car into the path of marshals standing on the pit-wall – thankfully just missing them -, Bottas pulled into his garage where the team determined the damage was enough to sideline him for the remaining hour.
Ahead of qualifying, the incident marks a blow for Bottas having shown impressive pace in Friday practice, headlined by a mammoth top speed of 351km/h.
It is the second time in three races that a loose drain has caused havoc after Nico Rosberg kicked up a cracked manhole cover in Monaco and the close-following Jenson Button struck it.
