The G&S Racing Kawasaki team travelled to Brands Hatch in Kent for round two of the National Superstock 1000 and 600 championships, but the weekend took a turn for the worse when 17-year-old Jordy De Jonge was involved in a multiple crash on the first lap of the Stock 600 event.
De Jonge had qualified well for the race but on the first lap he fell from his machine on Cooper Straight, while taking evasive action to avoid other fallers.
The race was immediately red flagged and he and the other rider involved, James Puttrell, from Hitchin, were treated trackside by the MSVR medical team.
They were then transferred to the circuit medical centre, where it was confirmed that Dutchman De Jonge - who is making his debut season in England - had suffered a serious head injury.
He was taken by air ambulance to the Royal London Hospital for further assessment and, as of today (Monday), he remains in the intensive care unit.
Earlier in the day Tom Fisher had secured a 23rd place finish to his Stock 1000 race for the Wyberton-based G&S team.
It was not where he wanted to be but it was a finish.
The short Indy circuit gives few overtaking opportunities and Fisher was unable to make much headway from his starting position on the eighth row.
In the Stock 600 event, Kevin Van Leuven began his race from the sixth row and worked his way up the field to complete the event in 13th position to pick up three championship points, bringing his total to 12 and placing him eighth in the rider standings.
