Banks-Browne, coming into the weekend fresh from his victory in Newcastle, had advanced to semi-final of the head-to-head battle after taking a third and a fourth in his two heat races and qualifying for the main event.
After taking the lead out the first corner, the Geartec Suzuki rider was involved in a collision with series leader Thomas Ramette on the SR75-Molson Suzuki, which saw the Frenchman attempt to make a pass on the inside but unfortunately clatter into Banks-Browne.
Banks-Browne suffered a broken tibia and fibia, ending his Arenacross season earlier and also affecting his preparation for this year’s British Motocross Championship.
Team Manager Rob Hooper, said afterwards, “Motocross can be so cruel.
Elliot was really looking like a regular winner, his riding was getting better and better, and now this injury – which was through no fault or mistake of his own – has destroyed his season.
“He will come back fitter, faster and stronger, but it will not be for a few months.”
