England subside to 325 all out before lunch
Sri Lanka's openers, Pathum Nissanka (1) and Dimuth Karunaratne (0), were not out in reply at the lunch interval.
Having started the day on 221 for three, the hosts, 2-0 up in the three-test series, gave up their remaining wickets steadily and cheaply, with the exception of Pope
Harry Brook (19) was dropped early on by Asitha Fernando but fell to Milan Rathnayake soon after, smashing a ball towards cover that Kamindu Mendis leapt to his right to catch.
Jamie Smith (16) then put up some resistance before smashing another ball into the hands of Mendis, and Chris Woakes (2) and Gus Atkinson (5) both lofted balls from Dhananjaya de Silva to Rathnayake.
Pope then finally succumbed, uncharacteristically swishing at one as well and being caught by Karunaratne off Vishwa Fernando. Pope had been under pressure after a run of low scores but silenced his critics with his seventh test century.
Olly Stone was not out on 15 but ran out of partners after Josh Hull (2) and Shoaib Bashir (1) put up little resistance to a much improved Sri Lankan bowling lineup.
