Troubled star AMY WINEHOUSE is facing more heartache after her father-in-law was seriously injured in a bicycle crash.

The singer, 24, and her incarcerated husband Blake Fielder-Civil are both said to be "deeply shocked and upset" after hearing of the accident.

Lance Fielder, 67, was racing his bicycle during circuit training near his home in Leicestershire, England, when he crashed his bike and flew over its handlebars.

He then spent three hours lying unnoticed in a ditch, according to reports.

After he was eventually spotted, Fielder was air-lifted to Queen's Medical Centre in Nottingham, England, where he underwent emergency surgery on for a spinal injury.

Medics fear he may be paralysed.

Fielder's wife Jane, a nurse, says, "At the moment, he's paralysed but it is too early to say if he will be permanently paralysed. I was really worried.

After calling the police I went out looking for him. By sheer fluke a lady in a tractor had seen his bicycle and spotted him lying in a ditch."

Blake Fielder-Civil is currently behind bars in London's Pentonville Prison after pleading not guilty to charges of attempting to pervert the course of justice after allegedly attempting to fix the outcome of a previous trial for grievous bodily harm.

He will stand trial for the latest charges in June.
