Valentino Rossi may have thrown away his tenth world title after a moment of madness from the "Greatest of all Time" means he'll start from the back of the grid at the season finale in Valencia.
After a hell of a battle between Rossi and Marc Marquez through the opening laps, both riders making audacious passes and giving no quarter, Rossi sat up going into turn 14, gave Marquez a look, and used his knee to force Marquez down. Have a look for yourself
Now, I've seen Rossi fans saying Marquez earned it. I've seen Marquez fans saying Rossi should have been disqualified. Well, speaking as a 15-year fan of Valentino Rossi, that is just not on. You cannot do that! Marquez is a racer, he's not just going to sit back and let Rossi get away. He wants to race, and it was a hell of a one before Rossi decided he'd had enough.
Dorna decided it wasn't worthy of losing his third place - he was a comfortable, distant third in the end - but they have given him a penalty - he will start from the back of the grid for the season-ending round in Valencia.
Further forwards, Dani Pedrosa rode a mature, confident race to lead from the front and the win was never in doubt. Jorge Lorenzo came second, and in doing so closed the gap up on Rossi at the top. It is definitely advantage Lorenzo with the penalty to Rossi, but the Italian has nobody to blame but himself.
Rossi is now saying that he may not even go to Valencia, and may leave the sport completely. I've never known him be like this, he's acting like a spoilt kid.
The Moto3 title isn't over yet, either - although things are a bit easier for the championship leader. Miguel Oliveira took the chequered flag, with Danny Kent coming in seventh - two places higher and the title would have been his. As it is, Kent leads Oliveira by 24 points, meaning a 14th place finish would be enough for the Brit to take the title in Valencia.
It will come as no surprise that Johann Zarco won the Moto2 race, although it may interest you that Tom Luthi led the race for a long period, Zarco doing what he does and pouncing at the last minute.
In two weeks time, the title will be decided. Will Vale turn up? Will he manage to win the title? Will Kent finally find the bottle? We'll find out in Valencia.
