  The Dundrod 150 Superbike race was cancelled due to deteriorating visibility after the initial race had been red-flagged following an incident, which was not serious.
  The leaders had completed two laps, with Michael Dunlop just in front of Bruce Anstey, Ian Hutchinson and lap-one leader Conor Cummins when proceedings were brought to a halt.
