The first day of the German Grand Prix began badly for the Repsol Honda team when Casey Stoner and Dani Pedrosa were among four riders to suffer big falls at Turn 11 this morning.
Stoner's accident was the most spectacular, the world championship leader bouncing off the front of his RCV after being unseated in a highside.
The Australian returned to set the second fastest lap time of the session, but the incident left him with a bruised arm and disrupted his plans.
"I'm not too happy with how today has gone, we had a crash second lap out in FP1 and this affected us quite a lot, we lost a lot of time coming in and changing leathers and then I had to go out on a bike that I wasn't quite as comfortable with, so apart from the last few laps, this morning's session was a bit of a waste for us," said Stoner.
Stoner finished the day in fourth place, 0.317sec behind Marco Simoncelli.
"Then this afternoon we tried the bike from this mornings crash but something wasn't quite right with it so we had to come back in and get on the other bike. We definitely made some progress, we started using hard tyres front and rear and made some positive steps but we still need to take a big step forward tomorrow.
"Our confidence was knocked today and I'm feeling a little sore still but we remain positive for tomorrow and hopefully we'll be able to close the gap a little more".
Pedrosa, riding in his second event since returning from a broken collarbone, fortunately avoided further injury in his Turn 11 lowside.
The Spaniard, winner of last year's event, went on to finish afternoon practice in a strong third place, 0.207sec from Simoncelli.
"I crashed in the fast downhill right hand corner, like everyone else because the tyre was very cold and I had no warning," said Pedrosa. "Fortunately I did not hurt myself which is good and in the afternoon I was able to improve my lap times because in the morning, after the crash, we didn't have much time on track.
