The mogul told his colleagues last week that he's on the road to recovery.
Media mogul Rupert Murdoch is at home recovering after he hurt his back while sailing, he told a group of senior colleagues in an email late last week.

Murdoch said in the missive that he's on the road to recovery from the incident, which has not been publicly disclosed. He estimated that he will be working from home for a few weeks.

Vanity Fair on Wednesday reported that Murdoch hurt himself "while vacationing on his son Lachlan’s yacht in the Caribbean earlier this month." Lachlan Murdoch also serves as executive chairman of the Fox News parent company.

A spokesman for 21st Century Fox said the company is not commenting on the report, which said that Murdoch had to be helicoptered off of his son's boat and was taken to a hospital in Los Angeles.
