Michael Clarke is at war with Cricket Australia and will be asked to explain to chief executive James Sutherland the comments that could ultimately threaten his future as Australian captain. Clarke was going to rule himself out of the first Test against India on Tuesday but the announcement from CA was put on hold because of the serious injury to Phil Hughes. Hughes and Clarke are close friends and the horrible accident at the Sydney Cricket Ground cast all other issues into the background. But key decision makers are furious with Clarke, and tensions with the selectors and the CA hierachy are mounting. It remains to be seen whether those bridges can be mended. They believe he has tried to run his own fitness race, in defiance of the agreed plan, in an unrealistic attempt to return from a recurring hamstring injury in time for the start of the series from December 4. The captain's public utterances have been at odds with those of team performance boss Pat Howard and chairman of selectors Rod Marsh, who needed to be convinced that Clarke could get through a Test without breaking down after injuring the same hamstring in the same spot three times in three months. Initially, CA wanted Clarke to prove his fitness in the Sheffield Shield game from Tuesday, but then relented and agreed to extend his fitness deadline to allow him to play in the two-day tour game against India from Friday. However Clarke confirmed at a personal sponsor's event on Monday night he would not be lining up for a CA XI in the tour game but instead wanted to play for his club side Western Suburbs. Before the news of Hughes' injury broke, Sutherland told Fairfax Media he wanted an explanation and that the issue of his fitness had teetered "off the rails". "I will speak to Michael and others who have been involved in the process to make sure I understand where these things have gone awry," he said. "It's not really appropriate for me to go into any more detail. All I can say is I am concerned that there are some mixed messages coming out of Cricket Australia in the last 24 hours or so and I want to understand why things have fallen off the rails a bit there." CA was appalled at the elaborate game of ducks and drakes in Sydney grade cricket on Saturday, when Western Suburbs declared at 0-17 in an effort to ensure Clarke would get a bat next week, prompting Cricket NSW to launch an investigation into the club's manipulation of the match. On Monday, Clarke was named in the Test squad to face India, and Marsh said Clarke's chances of leading his country at the Gabba were dependent on him emerging unscathed from the tour game in Adelaide. "What they have said is that he needs to start running, and if he doesn't start running by, I think, Wednesday, then I think we can safely assume that he won't be playing the Test match," Marsh said. Clarke seemingly wanted the selectors to trust him to make the right call on his fitness, taking into account that he has played 107 Tests and missed just one through injury, despite managing a chronic back injury since his teenage years and more recently battling back-related hamstring trouble. Another explanation is that Clarke simply wanted to play in any warm-up match and when physio Alex Kountouris told him he wouldn't make the tour game, he targeted the club fixture. Clarke's revised goal is likely to be the second Test in Adelaide from December 12, but CA would presumably still want him to play a warm-up game before then.
