A shadow has been cast over the future of Donington Park's British Superbike round as work to dig a tunnel under the track at the McLeans section has rendered the circuit unsafe.
As part of the effort to upgrade the track to full F1-status next year, a new tunnel has been built but it is only just as wide as the track and barriers currently in place are just feet from the edge.
British Superbike organisers Motorsport Vision have already cancelled a car event at the track next weekend on safety grounds because the sport's governing body the MSA has not, as yet, issued the circuit with valid full licence.
BSB Series director Stuart Higgs said: "We are watching the situation closely but we cannot hold an event at the track if it is not issued with a valid licence."
It is believed the Donington Park management team are confident the BSB round will go ahead in May as scheduled and the barrier on the outside of McLeans will be put back to were it was previously.
