US cable giant Comcast gate crashed the deal in February when it said it would offer 12.50 pounds a share to buy Sky, compared to Fox's 10.75 pounds, although it has not yet made a formal bid.
To ease concerns that Murdoch, who already owns The Times and The Sun newspapers in the United Kingdom as well as radio operations, would have too much influence over the United Kingdom media market, Disney has now "expressed interest" in buying the news network.
It is one of two proposals being made by Fox as it seeks to persuade the UK's Competition and Markets Authority to approve its £11.7 billion bid for Sky. The Murdoch family already own News UK, the owner of the Times and the Sun.

Activist hedge fund Elliott Capital has been building a substantial stake in Sky in recent months, and on Tuesday it disclosed its interest had grown to 2.84 percent. In February, Comcast jumped in with a competing $31 billion bid for Sky after missing out on the deal for Fox's entertainment assets that went to Disney.
The agency is mulling whether to recommend the Fox deal for Sky to Culture Secretary Matt Hancock for approval. Funding for Sky News would also be guaranteed for 15 years.
It provisionally ruled that Mr Murdoch would have too much influence over public opinion if the deal went ahead as planned.
Fox said it has "worked diligently" with the CMA throughout the regulator's review of the deal.
