MONTEGO BAY, St James — Defending IAAF World Championships men’s 100m champion Yohan Blake has withdrawn from the JAAA/Supreme Ventures National Senior Championships set to start at the National Stadium tomorrow morning.

A release from his manager, Cubie Seegobin, last night said, “Yohan’s coach is not satisfied with the progress of his injury, and hence his level of fitness will not allow him to compete at this time. We will continue to assess the situation and re-evaluate as we approach the World Championships.”

As defending champion in the 100m, Blake has a bye to this summer’s IAAF World Championships in Moscow, Russia, but it means he will not attempt the sprint double as he did last year at the London Olympics, coming away with two silver medals, both behind training partner Usain Bolt.

Blake competed two weeks ago when he ran a 200m race at a JAAA All-comers meet at the National Stadium in 20.72 seconds, his first outing since injuring his right hamstring at the UTech Classic in April.

Seegobin told the Jamaica Observer last night they were taking things “day to day, he is just not fit enough to race this weekend over 200 metre”.

Seegobin, who arrived in the island earlier this week, said Blake is scheduled to race at a meet in Edmonton, Canada, next weekend, June 29, but they would watch his progress.
