Australia captain Michael Clarke hints at fitness fears ahead of Ashes

Australia captain Michael Clarke has suggested that he may not be fit for the start of the Ashes series.

The 32-year-old has been marred by an ongoing back problem, which has put him out of the Aussies' one-day international series against India.

According to BBC Sport, when asked if he will be fit for the first Ashes Test against England, Clarke said: "I'll say definitely not [a chance of missing], but at this stage, we can't predict how long it's going to take to get right."

The opening Test of the return series gets underway on November 21.
