FP2 HIGHLIGHTS: Watch the key moments as Albon crashes and a dog interrupts practice in Bahrain
If first practice for this weekend's Bahrain Grand Prix was a fairly straightforward affair, FP2 was... less so.
Things were fairly routine for almost an hour, before Alex Albon suffered a big crash after running wide at the final corner and smashing his Red Bull into the barriers in what was a big shunt for the Thai driver.

The red flags were flown to halt the session while Albon's car was cleaned up, and he returned - thankfully unhurt - back to the pits. But the session had barely restarted when it was red flagged again, after a stray dog was spotted on the track.
In amongst all that, Lewis Hamilton completed a clean sweep of Friday running by finishing fastest, ahead of Max Verstappen and Valtteri Bottas.
