World junior scratch race cycling champion Geraint Thomas is in intensive care after crashing whilst training in Sydney, Australia.

The 18-year-old from Cardiff ruptured his spleen in the accident, but is expected to make a full recovery.
He hit a piece of metal in the road and suffered internal bleeding after falling on his handlebars.
Thomas will now miss this week's World Cup track meeting in Australia and next month's senior World Championships.
It was in Los Angeles last year that he continued an excellent season by clinching the World Scratch Race Championship.
In December, the former Whitchurch High School pupil was presented with a Carwyn James Junior Award at the BBC Wales Sports Personality of the Year ceremony.
David Evans of the Sports Council for Wales Elite Cymru programme, which has supported Thomas' career said: "Geraint is an outstanding talent and has been recognised by British Cycling as a potential Olympic medallist in Beijing.
"He is now making a breakthrough from a very successful junior career into the senior ranks. He has already achieved fantastic results at senior level, even though he's still only 18-years-old.
"Everyone from the Sports Council for Wales wishes him a full and speedy recovery."
