Full Friday free practice times from the Dutch MotoGP, round six of the 2010 world championship.

Marco Melandri ran straight on at the new, ultra-fast, Ruskenhoek turn after 12 minutes and suffered a big highside when he rejoined the track.

The Italian walked away holding his left arm and is being treated for a 'suspected shoulder dislocation'. He is 'doubtful' for qualifying.

Ducati's Nicky Hayden fell in the final minutes, but was unhurt.

Hiroshi Aoyama, injured last Sunday at Silverstone, has been replaced at Interwetten Honda by HRC test rider Kosuke Akiyoshi.
