Shane Watson Out Of Pakistan Series
Shane Watson will miss Australia's tour of the United Arab Emirates for a series of matches against Pakistan after suffering a setback in his rehabilitation from an ankle injury.
After initially spraining his ankle, Watson is now struggling with pain in his right calf - an area which has caused him significant trouble in the past.
With Cricket Australia (CA) ruling him out of any bowling work for up to 10 days, the decision has been taken to replace him in all three squads.
That timeframe would have ruled him out of the single Twenty20 game and three-match ODI series that gets the tour underway, as well as severely limit his preparation time for the two-Test series.
Australia can regain the number one ranking in Test cricket if they win both Tests, in Dubai and Abu Dhabi.
Richardson has played four ODIs for Australia and is yet to make his T20I debut.
"Shane has done everything he can to get up for this tour and left no doubt in our minds that he wanted to push through," National Selector Rod Marsh said.
"Had the decision been left to Shane, he would be on the plane to Dubai, however as selectors we have taken a conservative approach to ensure he has the best chance of being fit for the big summer ahead," he added.
It is the second injury blow to have struck Australia in a matter of days after captain Michael Clarke was ruled out of the ODI series.
Hughes was added to the ODI squad as cover.
