Nigeria will undertake an overhaul of its international sports program after it failed to win a medal at the Olympics, President Goodluck Jonathan ordered. Jonathan advocated a retreat for government, business and sports organizations to meet and discuss ways to invigorate sports in the country, Nigerian newspaper This Day reported Friday. He \"ordered a total and comprehensive re-organization of the sporting sector, following the disappointing performance of the Nigerian contingent\" at the recently concluded Summer Olympics in London, Information Minister Labaran Maku said. Nigeria, Africa\'s most populous country, spent $13 million on its Olympic effort, the BBC reported. It won four medals at the 2008 Olympics in Beijing.
