More Thorpe doubts about his commitment

Ian Thorpe's swimming career is up in the air with the five-time Olympic champion in danger of missing next year's world championships in Melbourne. The 24-year-old has been tipped to skip the selection trials starting in Brisbane on December 3, which would rule him out of the worlds, after being ravaged by illness and injury this year. Thorpe is understood to have missed several training sessions since returning to Australia from a three-month sojourn in Los Angeles in October. A Swimming Australia insider told AAP that Thorpe was not expected to swim in Brisbane. "I am concerned that it is moving down that track," the source said.
