Aspar Honda’s Nicky Hayden has broken his right thumb in a minimoto accident and is unsure whether he will be able to race in Sunday’s Aragon MotoGP round.

The American will see how the injury is on Friday at the Spanish track and says he is optimistic but only time will tell.

“Aragon is next, it's quite a unique track with a lot of elevation and it's quite technical, with some blind entries and downhill braking. It's certainly not an easy track and I haven't made it any easier this year because I had a little accident training on minimotos in Italy and broke my thumb. I have seen the doctors and had the scans and I am optimistic I'll still be able to race but we will have to see on Friday how I feel,” said Hayden.

“Unfortunately it's the right thumb, which is always a little bit worse, but I have been doing a lot of therapy in the last days and I definitely feel a bit better. We weren't having an easy season as it is and this won't make it easier but injuries are as much a part of this game as finding a set-up for your bike! Hopefully we can go there and still have a positive weekend.”
