A loose drain cover brought an early end to the Friday's first practice session for the Azerbaijan Grand Prix after George Russell ran over it and damaged the underside of his Williams. 

Only 12 of the session's 90 minutes had elapsed when Russell, rocketing down one of the track's ultra-fast straights, struck the dislodged manhole cover, destroying the floor of his car in a shower of debris.
The 21-year-old was unhurt. But needing a new chassis, he sat out the second of Friday's two sessions as a result. The soonest he can to the track will be today's final hour of practice running before qualifying, the team said.
