Usain Bolt withdraws from Jamaican national championship

San Juan: Jamaican sprinter Usain Bolt is not participating in the Jamaica Athletics Administrative Association National Senior Championship.

The six-time Olympic champion is already guaranteed a spot on the Jamaican team competing in the August 22-30 World Championships in Beijing, where Bolt will defend his 100 metre and 200m titles, reports Efe.

Bolt's agent Rick Simms said the runner was not "confirmed" to take part in the Jamaican trials for Beijing, but had signed up only "to have the option" to run.

The world record-holder was expected to vie with Asafa Powell, Yohan Blake, Kemar Bailey-Cole, Nesta Carter and Nickel Ashmeade at the senior championship in Kingston, the Jamaica Observer newspaper reported Friday.

A spokeswoman for the JAAA declined to provide more details on Bolt's withdrawal.
