Yamaha factory rider Valentino Rossi has been demoted to the 20th position in the first practice session of the Australian MotoGP race held at the Phillip Island race track.
In wet and slippery conditions, Rossi managed to clock a time of 1m40.998s and was in the second position behind pacesetter Cal Crutchlow in free practice one.
But Rossi's run of 11 laps during which he posted his best time was invalidated as the Yamaha rider exceeded the maximum laps allowed in a single stint on the Michelin super soft wet front tyre.
So, Rossi's stint of 11 laps was deducted from his free practice one session and was only left with what he managed to do in the second run of the session when the track conditions further deteriorated.
That means Rossi's best time for the first session of free practice was 1m47.225s, and the Italian is slotted in 20th position behind his teammate Jorge Lorenzo who struggled in the wet conditions.
An official statement read, "Valentino Rossi was found to have used the 1008B Super Soft Full Wet Front Tyre more than 10 laps, so he was imposed a cancellation of the lap times during the run where the 1008B tyre was used illegally (the run of more than 10 laps)."
If the conditions at the Phillip Island circuit does not improve on Saturday, Rossi will find himself outside top ten positions after the third practice session. And therefore will have to fight his way through the first qualifying session.
