It was not clear who had taken and shared the photo of Chris Smalling on a hospital bed in Bali.

Manchester United's Chris Smalling has been taken to hospital with food poisoning after fainting in Bali, although for a while it seemed the England defender might have suffered a more serious problem.

A picture of Smalling was posted on Twitter with a bandage around his head, a brace on his neck and a drip coming out of his arm - and signing a football jersey.

The post suggested he had been hurt while having a surfing lesson while other reports said he had been stung by a jellyfish.

The truth, however, proved more mundane and the 26-year-old, who played for England at Euro 2016, had now fully recovered.

"Chris has had food poisoning during his holiday which resulted in him fainting yesterday. He was taken to the hospital and is now feeling fine," a United spokesman said on Monday.

Smalling was on vacation in Bali following England's Euro 2016 knockout in a 2-1 loss to Iceland, and would return home for pre-season training later this month, the team said.

"Chris would like to thank everyone for their well wishes."
