Friday’s second practice session in Turkey faced a long delay when a drain cover worked loose.
Twenty two minutes into the 90-minute session, the red flags began waving and the action did not resume for nearly half an hour.
The scene at turn 10 was investigated by marshals and the FIA’s Charlie Whiting, amid suggestions that Rubens Barrichello actually ran over the errant debris.
It was initially dislodged when Giancarlo Fisichella ran over it, and safely re-secured before the action resumed.
