Centre Jonathan Joseph has grabbed two tries as England gained their second win in the Six Nations Championship and swept aside a brave Italian side 47-17 with a dominant second half display at Twickenham.

No.8 Billy Vunipola, scrum-half Ben Youngs and replacements Danny Cipriani and Nick Easter also went over for England, who again fell behind in a game before rallying and then surging clear.

They had been stunned by a fine early try from Italy captain Sergio Parisse while centre Luca Morisi also crossed twice for the visitors in the second half.

England fullback Mike Brown became rugby’s latest concussion victim as he was knocked cold and out of the match after just 12 minutes. His head collided with the shoulder of Italy centre Andrea Masi and he was treated on the field before being taken off on a stretcher.

But he soon recovered and was not taken to hospital but took a seat in the dugout to watch the rest of the match.

“It’s going great. It’s great to get the win today. The boys showed great spirit to come back and get the win,” Joseph, who ended up on the wing after Brown went off, told the BBC.

England eventually ran out easy winners with a strong second half display against a tiring Italian side, which had been beaten 26-3 by the Irish in Rome the week before.

The visitors had not scored a Test try for 254 minutes. Yet they stunned England after just three minutes as the powerful Parisse, who grabbed the previous one against Samoa in November, bull-dozed his way over.

“It was a soft try we conceded first up. At half-time we give them a rev up, said we needed to up the intensity, and I think we did that in the second half,” said England coach Stuart Lancaster.

“Slightly disappointed that we didn’t do a bit better but I’m really pleased for Jonathan Joseph. He’s having a great season so far and I’m delighted for him.”

England lost Brown with concussion in a painful collision early in the game as he attempted to intercept fly-half Kelly Haimona’s chip through.

As he went to catch the ball, Masi got to it first and the Italian’s right shoulder clattered into the side of Brown’s head.

Brown was left flat out on the grass unmoving and with blood dripping from his nose.
