Finally the breakthrough for India! And it's a beauty of a ball from Chahal that does for Buttler, pitching on leg, straightening and hitting the pad plumb in front as the batsman plays down the wrong line.
James Anderson took a fine catch over his shoulder to dismiss Dinesh Chandimal on day four of England's second and final Test in Sri Lanka.
A neatly-clipped leg-side single off Dilruwan takes Sibley to a 139-ball, third Test fifty, to go with two centuries.
Ten wickets in the match for Lasith Embuldeniya. Dan Lawrence is out in unfortunate circumstances. He inside edges the ball on to his pad, and Dickwella takes a sharp catch behind the stumps.
Root was looking in total control, but having hit Ramesh Mendis for a delightful drive through mid-off with the previous delivery, he goes too far across his stumps and as he attempts to sweep, he drags it on to the stumps off his glove and he is bowled.
Very useful innings from Bairstow, but he's trapped LBW courtesy of a quicker delivery from Embuldeniya.
Embuldeniya gets the ball to explode out of the surface and it takes the glove and goes to Fernando at gully.
Two in two for Joe Root! Wide half-volley from the England captain, and Fernando plays on and is bowled with his very first delivery.
The left-hander is denied a maiden Test fifty as he guides the ball to Bairstow at slip, who takes a comfortable catch.
Ramesh Mendis goes for the sweep but gets a bottom edge on to his boot and Buttler takes the catch!
It's another fine grab from Zak Crawley at short leg! Dilruwan attempts to work the ball into the legside, but he flicks it straight to Crawley and it's like catching practice for the England opener, as Bess picks up his fourth wicket!
Another one for Bess! Dickwella tries to thrash the ball through the offside but hits it straight to Dan Lawrence at short extra cover, who holds on to a low catch. What a morning for England!
Leach tries to sweep, misses and is hit plumb in front. England have two reviews remaining so he tries his luck but to no avail, three reds and that is the end of the innings.
Jack Leach strikes with his second ball! Perera sweeps, misses and that looks adjacent! The umpire agrees and up goes the finger. The batsman reviews but height is the only thing that could save him... it doesn't, umpire's call. Good start for England!
Brilliant catch from Zak Crawley! He's in at short leg but this is not a bat-pad, this is off the face of the bat as Thirimanne as he tried to work Leach through the legside and he clings on superbly!
Massive wicket for England! Mathews on the sweep again to Bess, he misses, there is a hint of spin and the ball thuds into off stump.
That's the one Bess was after! Good attacking line outside off, turning in sharply to the right-hander, inside edge onto pad and the ball pops up to Zak Crawley at short leg. Sri Lanka two down early.
Joe Root was run out for 186 from the final ball of the day as another magnificent innings from the England captain came to a close.
Root not amused as Wood goes for a massive slog sweep and top-edges to slip. Embuldeniya has seven wickets.
Bess edges cleanly to Thirimanne at slip, via a deflection off Dickwella's glove. Six wickets for Embuldeniya.
