The Redcar Bears speedway team have suffered the loss of their number one rider Jason Lyons in a fall during the Premier League fixture at Glasgow on Sunday afternoon.
Jason hit a hole on the first bend during the fifth heat and sustained a triple fracture to a femur.
Boss Brian Havelock said: “This is a devastating blow for both rider and club.
“Easier said than done but I would prefer to sign another rider rather than use guests and I am urgently considering the options available.
“Our next league match is away at Scunthorpe on Friday (9 Sept) so time is of the essence.”
