Dalton is understood to have crashed yesterday while competing in a qualifying race for the 23rd International Island Classic at the Phillip Island Grand Prix Circuit in Victoria, Australia.

According to the report of the race - which was delayed because of heavy rain - by Motorcycle Dalton crashed 15 minutes into the session.

"...the session was brought to a halt halfway into the 15-minute session when Grant Dalton went down on the exit of turn three. It's unknown if he went down on his own oil or that left by another machine," the report said.


"Dalton suffered a broken wrist in the tumble."

After Dalton's crash, four more riders slipped in the slick and the race was cancelled.
