Bolt must qualify for Jamaica 100m team
Usain Bolt will have to qualify at the Jamaica National Senior Trials to book a spot in his country's 100 metre team at the World Championships.
The six-time Olympic gold medallist has been overlooked in favour of training partner Yohan Blake - world champion two years ago following Bolt's disqualification for a false start.
The decision means Bolt will head to Jamaica's National Stadium to run heats on June 20, with the semi-finals and final held the following day.
A top-three finish for the 26-year-old will guarantee selection for August's World Championships in Moscow in the individual 100m and Jamaica's 4 x 100m relay team.
New IAAF rules introduced last year give defending world champions and Diamond League winners automatic entry into the World Championships. But if a country has two eligible candidates, then that nation's governing body must make a decision.
Despite Bolt winning the 100m Diamond League title, the Jamaica Athletics Administrative Association must defer to Blake in the short sprint.
In turn, 2012 Diamond League winner Nickel Ashmeade will see Bolt take the only automatic 200m slot because he is the reigning world champion over the longer distance.
It means Bolt, who has had a sluggish start to this season, will not have to face Blake at qualifying, with Blake not needing to run the 100m and Bolt not requiring qualification for the 200m.
