Buriram, Thailand: Andrea Dovizioso sped to the fastest lap in practice for the inaugural Thailand MotoGP on Friday as his Ducati team-mate Jorge Lorenzo was passed fit for the weekend despite a heavy crash.
Dovizioso led the second session with a lap of 1min 31.090sec, 0.031 ahead of Movistar Yamaha rider Maverick Vinales who had topped the morning timesheets.
Repsol Honda's Marc Marquez, who leads Dovizioso by 72 points as he closes in on a fifth MotoGP world title, was fourth quickest in the afternoon session.
But much attention focused on the nasty spill by Lorenzo, who was already dealing with a foot injury sustained in Aragon last month.
He was cleared to race Thursday but told reporters he was still in pain and could be seen limping.
About halfway through the second practice Lorenzo crashed, tumbling across the track as his bike broke into pieces, temporarily stopping the session.
MotoGP tweeted afterwards that Lorenzo was undergoing further medical examinations but "has been declared fit" to race following his accident.
Thailand is hosting its first MotoGP in Buriram, a sleepy town several hours' drive from the Thai capital Bangkok.
