The van was discovered in the river early on Tuesday morning (August 13), near London Road bridge.
It is not known how the vehicle entered the water.
A hole appears to have been made in the rear door, which is visible from the banks of the river (see picture).
Lancashire Police said a man has been taken to Royal Preston Hospital. No arrests were made.
