The FIM have revealed a further tweak to the 2010 MotoGP calendar, with the Czech Republic Grand Prix being moved for a second time in just a week.

The round, held at Brno, was originally switched to the date of 22nd August, but will now take place a week earlier on 15th August.

The decision means the summer break will now be little more than three weeks, while it also leaves a week's gap between that and the next overseas event at Indianapolis.

The latest provisional calendar is as follows...
