Bookmakers have slashed the odds of Ozzy Osbourne reaching Christmas number one following the star’s accident.

An outpouring of public sympathy for the crooked rock God – currently on a ventilator in a Slough hospital – has led William Hill to cut their odds from 50-1 to 16-1. They say they have been inundated with a “sudden flood of money” from punters backing ‘Changes’, the Black Sabbath track Ozzy has re-recorded with daughter Kelly.

However, the 12 Pop Idol finalists are still 1-3 favourites with their version of John Lennon’s ’Happy Xmas (War Is Over)’.The Darkness remain a 3/1 bet.

Meanwhile, doctors have revealed that it could take up to two months for Ozzy to recover from his injuries.

Osbourne broke eight ribs, his collarbone and cracked a vertebrae in his neck when he crashed his quad-bike on his Buckinghamshire estate yesterday. He was taken to the nearby Wrexham Park Hospital where he had emergency surgery to correct the collarbone and fix damaged blood vessels.

“How long treatment will take depends on the severity of the injuries and what happens in the first few days,” said Dr Bentley, assistant medical director at BUPA told ananova. “It sounds like he is having all the right treatment done.

“He is in intensive care on a ventilator. The reason for this is because when someone breaks that many ribs and his collar bone it makes it difficult to breathe. They tend to take only shallow breaths because of the pain caused by their injuries.”
