England coach Eddie Jones insisted the "world hasn't ended" after a stunning second-half collapse saw his side suffer a 21-13 Six Nations defeat by Wales in Cardiff.

Saturday's reverse ended England's hopes of a Grand Slam this season, with Wales now the only side left in the Championship who can complete a clean sweep.

"The world hasn't ended. I guarantee you the world's still out there and we'll learn from this," Jones said after his first defeat as England coach in five Tests against Wales.

"They beat us in the air, the penalty count was lopsided [England conceded nine penalties to Wales' three] and when you are getting beaten in those two areas when it's a tight game, you are going to struggle to get the result you want."

England were 10-3 ahead at the break following Tom Curry's try. Wales got back into contention through two Gareth Anscombe penalties conceded by England prop Kyle Sinckler, who was promptly taken off by Jones.

England captain Owen Farrell's penalty made it 13-9 before Wales went ahead for the first time through lock Cory Hill's 67th-minute try.

Replacement fly-half Dan Biggar added the conversion before confirming Wales' aerial superiority with a precise cross-kick caught by wing Josh Adams for the clinching try two minutes from time.

Wales coach Warren Gatland had labelled Sinckler an emotional "time-bomb" in the lead-up to the match.

But the New Zealander, who will stand down as Wales coach after this year's World Cup in Japan, was slightly more complimentary after the final whistle.

"He's a fantastic rugby player, but he does have a few demons to deal with," said Gatland, who coached Sinckler during the 2017 British & Irish Lions' drawn series in New Zealand.

But Jones defended the Harlequins front-row by saying: "I didn't know Warren had a degree in clinical psychology, so let me know and I might go and see him as well.

"We just felt it was the opportune time to make a change ... He was starting to get a little bit tired.

"I know you guys [the media] want to single him out because Warren said what he said, but don't be unfair to him. He's a young player on the way up. Look after him a bit."
