Tomorrow's (Sat) opening TT practice session could be cancelled unless extra marshals sign-on.
Although the overall level of signing-on has been very positive with over a thousand volunteering their services, the first session is traditionally difficult to staff.
Around another twenty are needed to reach minimum levels and there is a further chance to register interest at the Villa Marina Promenade Suite from 7 o'clock this evening.
Isle of Man T.T. Marshals Association Chairman Bill Carden says if not enough marshals are in place for a practice or race session, the decision is simple:
MHK calls for citizen's jury to look into legalising recreational cannabis
Teenager's petition calls for more funding for the Island's music service
Charities partnering for coast-to-coast cycling challenge in Scotland
Photo ID requirements could create 'faff' at borders, says Steam Packet boss
