It's been a dramatic turnaround in the evening sunshine at the Riverside with Chris Rushworth claiming three wickets with the second new ball for a five-wicket haul.

The Durham paceman had already claimed his 500th wicket for his county when he uprooted Aneurin Donald's off-stump.
David Lloyd on 7 then fell lbw as Rushworth celebrated his fifth of the day, and Matthew Potts had debutant Tom Cullen caught at slip, also for 7.
