Chris Vermeulen's torrid 2011 World Superbike campaign will continue into the latter portion of the season after it was confirmed he will be forced to miss the tenth round at the Nurburgring because of persistent injury woes.

The Australian has suffered a myriad of problems since he re-joined the series with Kawasaki in 2010, but having now sufficiently recovered from the knee injury that kept him on the sidelines for almost a year, an elbow injury picked up at Monza is now proving troublesome.

Indeed, Vermeulen has started just six races this season, with the Australian opting out of the previous event at Silverstone altogether in an effort to come back from the summer break fully fit. However, Vermeulen will not be present on the ZX-10R in Germany as he has not been declared '100 per cent'

"Kawasaki wants the doctor to give me 100 per cent on my arm before I race," Vermeulen is quoted as saying by Fox Sports Australia. "I will start testing next week for Imola."

Though Vermeulen won't race at the Nurburgring, Kawasaki will welcome back Tom Sykes, who was forced to miss Silverstone after injuring his ankle in a free practice crash.
