The summery conditions returned to the Mountain Course for the final night of practice week.
But an oil spill at Barregarrow during the Supertwin / newcomers session meant the final session - for Superbike, Superstock and Supersport machines - was called off as riders were waiting to go out.
The sidecars were out first tonight, to road test a few last adjustments and bed-in tyres ahead of tomorrow afternoon's race.

The six-lap Dainese Superbike race starts at 11am tomorrow, followed by the three-lap Sure Sidecar 1 race at 2pm.
