Wednesday evening's qualifying session at the Isle of Man TT has been cancelled due to the weather.
It's the third session which has been called off this week.
As a result, the organisers are now planning an additional qualifying slot for Thursday afternoon.
Dean Harrison set the pace in the first Superbike session on Tuesday and also topped the Superstock class.
The Clerk of the Course Gary Thompson says plans are already in place to race on Sunday if the weather doesn't improve.
The forecast suggests there could be further disruption to come over the next couple of days.
Thompson confirmed there could be an additional qualifying session on Saturday rather than racing.
