Marlboro Ducati's Nicky Hayden thinks he will not see the same aluminium chassis upgrade that team-mate Valentino Rossi will ride with in first MotoGP free practice tomorrow until the Valencia test in November.

Rossi tested the chassis at Mugello last week and his bikes have already been seen in pitlane but Hayden says won't get to use them this season.

'I am not going to get it this year. I spoke with Filippo a couple of times and it seems real positive, they're pretty happy around there and we will see how Valentino goes and how it translates for the race weekend," said Hayden, speaking to bikesportnews.com this evening.
