Picture sequence from Crash.net's photographers Gold & Goose showing the first lap collision between Jack Miller and Hector Barbera at Assen on Saturday.

Fortunately both riders were unhurt, despite Barbera getting his leg caught in Miller's rear wheel and the Australian somersaulting from his LCR Honda...

"I'm angry, because it's sickening when things like this happen," said Barbera. "I was looking forward to this race, in Barcelona was the same and I couldn't show my performance, and here it happened again...

"The race was finished for me before I complete the first lap, Miller missed the brakes going in to the last chicane and he hit me. I don't really know was he was thinking about, because it was impossible for him to make the turn. I was lucky to walk away unhurt because it was a bad crash; my right leg was caught with the rear wheel of his bike.

" I know Miller is a rookie, he has no experience with these bikes, but you have to be clever, because the race was 26 laps, and you can't win in the first one. This is racing and now we have to think in Germany."

Miller said: "I got a really good start and had a small touch with Eugene Laverty off the line, but after that I recovered. Coming into the last corner I tried to pass Bautista but my rear tyre overtook my front tyre and I got a little nudge from someone. It was unfortunate because I felt quite good here all weekend and my pace wasn't so bad, so to end it like this was a shame."
