Rules say...
A Reduced facility (No Facility in British Development) only, is permitted to replace a rider, who although included in a re-declaration has not made an appearance for that team since being re-declared.
however there is another rule that says....
A team may utilise a facility to cover the absence of a rider(s) who has been approved in a teams declared 1-7 at the start of the season but due to extenuating circumstances is not available, a facility may be granted, up to a maximum of 28 days, at the SCB Co-Ordinators discretion.
So I guess changes maybe on the cards for Redcar.
