Fixi Suzuki's John Hopkins is in serious doubt for next weekend's Donington World Superbike round after confirming he has broken his right foot in a crash at Monza's Parabolica today.

The American was spat off his GSX-R1000 on the exit of the fast right-hander just before the race was stopped for rain and he knows faces an assessment of just how bad the damage is.

"That was not a good weekend. I got pretty banged up in the first race crash and damaged my left hip and broke a bone in my right foot. I don't know what happened because the bike suddenly let go without any warning. It's a big shame because I had been really looking forward to this weekend and continuing my improvement. Today's conditions were treacherous and all the changes of weather didn't help at all. There was no way we could ride on the wets, so the right decisions were made," said Hopkins.
