UPDATE: Monday afternoon Tweet from Repsol Honda:
"Dani is feeling better and at the moment the plan is to be in Laguna! Thank you for all your kind messages."
Dani Pedrosa has revealed he was originally intending to race in the German MotoGP at the Sachsenring after initially being declared fit to race, but decided against it after suffering spells of dizziness and sickness.
The Repsol Honda rider, then leading the championship, was diagnosed with a small fracture to his collarbone after falling hard during FP3, but was passed fit to take part in the warm-up on Sunday morning.
However, Pedrosa took a turn for the worse just prior to heading out on track. Following another check-up by medical staff, he was declared unfit to participate.
"This morning I had my check up in the medical centre and I felt okay, my shoulder was painful but otherwise I felt fine. The doctors declared me fit to take part in warm up. Then shortly before the session I began to feel dizzy again and my blood pressure dropped.
“The doctors came to see me in my truck and we decided I shouldn't take part in the session. I returned to my motorhome to rest and still felt dizzy and sick. The doctors arrived at my motorhome and informed me that they did not consider I was okay to race and would therefore declare me unfit."
With the United States Grand Prix less than a week away, it is uncertain whether Pedrosa - who lost his series lead to Marc Marquez following his team-mate's victory in Germany - will participate.
With reigning champion Jorge Lorenzo also absent on Sunday - due to a collarbone injury - Marquez, Pedrosa and Lorenzo are now covered by just eleven points at the top of the standings.
Lorenzo has suggested he will not ride at the US GP but Yamaha state that the final decision is yet to be made.
