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:
Manx Care CEO to step down
Government "selling Garff down the river" for windfarm project, says local authority chair
MHK seeking horse tram answers from government ministers
Public urged to open 'home and heart' to children in need
