New Moto2 World Championship leader Marc Marquez was involved in a brutal crash at the very end of the first free practice session of the Australian GP at Phillip Island on Friday.
Marquez, seeking to make up for time lost in an earlier fall, struck the back of a slower-moving Ratthapark Wilairot (Thai Honda Singha SAG) through turn two after the chequered flag.
Marquez had righted his Repsol Suter bike in an attempt to brake, but the collision was unavoidable.
Both bikes were heavily damaged, Wilairot was airlifted to hospital while Marquez walked away from the incident with minor injuries.
Moto2 rookie Marquez holds the title lead by a single point from Stefan Bradl, who led the morning session despite a fall of his own.
Second practice takes place this afternoon.
