Ryan Harris chooses rest over riches in bid to be fit for Ashes Ryan Harris is focusing on a return for this summer's Ashes series. AUSTRALIAN spearhead Ryan Harris has listened to his body - prepared to forgo a lucrative Champions League tilt to underpin another bumper Ashes campaign. Australia's most valuable Ashes asset against England has been sidelined for six to eight weeks with a hamstring strain but told The Advertiser it was a 'precautionary' move. Having been grounded by knee, ankle, shoulder and Achilles injuries over the past three years Harris, 33, rates his latest ailment a blip on the radar. A worst case scenario would leave Harris under a month to gain match fitness with Queensland ahead of the return Ashes bout with England from November 21 at the Gabba. "It is not serious but just being cautious with it," said Harris, who hurt his hamstring on the final day of the fifth Test at The Oval. Deep down I know my body, if I have done something bad or not, if it will go away. Having scans you usually know how bad they will be. Harris revealed a charge to the boundary while fielding late in the drawn final Test at The Oval aggravated an injury that he initially did not believe would mean any time away from play. "Michael (Clarke) asked how I was, I said I wanted to bowl but chased a ball to the fence which I wasn't supposed to do and it got a little bit worse," said Harris, illustrating why he was tagged the ultimate team man by skipper Clarke. Harris succeeded in an ambition not to miss any Ashes games due to injury but the effects of 162.1 stellar overs for 24 English wickets at 19.58 in four Tests finally caught up with Australia's player of the series. Harris said the decision to miss next month's Champions League for Brisbane Heat and one-day tour to India during October was rightfully "Cricket Australia's call." Harris broke down with an Achilles strain representing Darren Lehmann's King's XI Punjab in April and Cricket Australia understandably want to protect the speedster vital to regaining the Ashes. "He was assessed after arriving back in Australia today and is expected to be unavailable to play for the next 6-8 weeks," said a CA spokesman. Harris attributed his brilliant Ashes campaign to hard work and precise plans to England's batsmen, particularly skipper Alastair Cook and Jonathan Trott but said individual honours were overshadowed by a 3-0 loss. To get through the four Tests was good but at the end of the day the results were bad. The good thing is they come back here in November and we can try and get the urn back then.
