Bolt to lead Jamaican team

Olympic champions Usain Bolt and Shelly-Ann Fraser-Pryce headline a Jamaican world athletics championships squad that will come under intense scrutiny in Moscow following several positive doping tests by some of the country's athletes. Neither Asafa Powell nor Sherone Simpson, both of whom tested positive for the stimulant oxilophrine, were included on the squad named by the Jamaica Athletics Administrative Association on Monday for the Aug 10-18 championships in the Russian capital.
