Oil on the track at Assen has forced the cancellation of all MotoGP and support class second practice sessions at Assen this afternoon. Bosses have been using water and detergent to remove the fluid for the past hour but to no avail after Moto2 rider Alex Baldolini managed to blow his engine and ride around the track with oil escaping from the bike.

This is the new schedule for tomorrow morning, qualifying sessions are as usual:

125 8.40-9.40

MotoGP 9.50-11.20

Moto2 11.30-12.35
