Airwaves Ducati's Shane Byrne could have ruled himself out of action for the rest of the weekend after a crash in this afternoon's second free practice session has left him with tissue damage to his left shoulder and a missing tooth.
The Airwaves Ducati rider only completed four laps before highsiding out of the exit of the chicane to then be hit by his own Ducati 1098R before stopping on the inside of the circuit.  The session was red flagged as the marshals and medical staff dealt with the incident.
"It was a third gear highside on the chicane; it was strange because I went through the turn no differently to any other time I have this weekend but the rear came out on me and the bike launched me up into quite a big one," said Byrne.
"I am generally ok; I have bruised my shoulder which is sore and a bit stiff, I’ve also got a bit of a dead leg and I have knocked my front teeth out. I should be able to get myself fixed up and I will be ok but I will need to have a medical in the morning and we will take a view on it after that."
Byrne is, at present, is unfit to ride and will undergo another fitness check tomorrow morning prior to the third practice session to determine whether he is allowed on track. 
He was hoping to clinch the British Championship 2008 title this weekend in which he currently leads by 110 points, but he may now have to wait a bit longer.
Rizla Suzuki's Tom Sykes headed the second free practice timesheets with the HM Plant Honda pairing of Leon Haslam and Cal Crutchlow in close attendance.
