Alvaro Bautista has apologised to MotoGP title leader Jorge Lorenzo and his own Honda Gresini team for his turn one error in the Dutch TT at Assen.
Starting eighth on the grid, Bautista dived for the inside at turn one, but missed his braking point, fell and then collected Lorenzo ahead of him.
Race Direction has punished Bautista with a back of the grid start at next weekend's German MotoGP round.
“Unfortunately, when I followed Dovizioso's wheel I lost my braking point and hit the brakes far too late. I tried to slow the bike down, but lost grip on the front and lowsided,” said Bautista.
“I am very disappointed, even more so because I took out Lorenzo in the process and that was the last thing that I wanted to happen. It was my fault that he crashed out and I apologise profusely to him for that. I hope that nothing similar ever happens again.
“I also apologise to my team, because they worked so hard this week, only to miss out on what could have been a great result due to this mistake.”
Bautista had arrived at Assen fresh from a debut pole and MotoGP best of fourth at Silverstone, although a fall in qualifying left him on the third row of the grid.
The race accident resulted in Lorenzo's 25-point lead over Casey Stoner disappearing, after the Australian went on to win the grand prix.
“It is a shame about the early crash. Alvaro really didn't mean it. I am very unhappy, because the crash caught the World Championship leader, Lorenzo, up in it,” said team principal Fausto Gresini
“We are sad that it turned out this way and Álvaro has of course said that it was not intentional. He was trying to gain places but he lost his braking reference and hit the brakes too hard when the tyres were not up to temperature.
“That meant that he lost grip and that he slid into Lorenzo.”
Fourth place Cal Crutchlow was also forced off track in the incident and rejoined at the back of the field.
