Dani Pedrosa has explained the circumstances that led to his shocking crash late in Friday's second practice session ahead of the Japanese MotoGP.
The Repsol Ronda rider, who won last year's race, was hurled into the air at turn 11 as he lost control of his bike.
Pedrosa fractured his collarbone in the incident and is now expected to return to Spain to undergo surgery on the injury, with no timeframe yet placed on his recovery.
"I'm obviously very sad about what happened, as I was looking forward to racing in Japan at Honda's home circuit and one of my favourite tracks," he said.
"I was on the out-lap of my last run in FP2 when I momentarily lost the rear entering turn 11, and when the tyre found grip again it launched me in the air.
"There's not much more to say; now I just want to focus on recovering in order to get back on my bike as soon as possible.
"My best wishes to Hiro [Aoyama], who is replacing me and will race in front of his home crowd."
Pedrosa sits fourth in the riders' standings with four races to come.
