Charles Leclerc set the pace in the morning session of day two of pre-season testing in Bahrain, before causing running to be curtailed early after destroying the floor of his car by hitting a loose drain cover.
The drain cover drama knocked nearly two hours out of the session after Leclerc and Lewis Hamilton ran over and destroyed a cover on turn 11, appearing to result in damage to both cars.
After 30 minutes of track inspections, it was announced by the FIA that the session would not resume and that the afternoon session would be extended to five hours
