Xerox Ducati's Noriyukik Haga had a CAT can last night which revealed the injury to his vertebrae was sustained in an earlier crash and is not as serious as first thought.

The Japanese rider did damage his left shoulder blade and fracture his right forearm which will take time to heal after surgery but Haga could be fit for the next round at Brno in a month's time. He is to undergo surgery this afternoon to insert a plate and screws in his right forearm, to set a fracture to the right ulna. He is continuing to experience pain in the left shoulder blade, and so although no serious damage has yet been detected, doctors will investigate further to understand the cause of the pain.

A spokesman for the team said: "The only injury needing immediate treatment at this time is the broken ulna. If the surgery is deemed a success, and there are no complications regarding his shoulder blade, Noriyuki should be able to return home to Italy in the next two days and the Ducati Xerox Team does not currently exclude the possibility of Noriyuki’s return to the track in time for the next round in the Czech Republic."
