Saturday's scheduled World Superbike race at Assen in the Netherlands has been delayed until Sunday because of heavy snow showers at the circuit.

The opening race of the weekend had been scheduled for 13:00 BST but the weather made track conditions unsafe.

Italian Alvaro Bautista secured pole position in Saturday's Superpole session, with world champion Jonathan Rea on the fourth row in eighth spot.

Bautista leads the championship by 39 points from Rea after three rounds.
