PARIS (AFP) - Jamaica's Olympic sprint champion Usain Bolt, currently recovering from a foot injury, said on Friday he is not ready to race at meets in Ostrava or Paris.

World record holder Bolt had been expected to make his return on the track at Ostrava in the Czech Republic on June 17 with the Diamond League meet in Paris on July 5.

The six-time Olympic champion said, however, that he was not ready to return after missing several weeks of training in March and April.

"Unfortunately due to the training that I missed I am behind where I am at normally at this time of year and will not be ready to race in the Ostrava Golden Spike meet or Meeting Areva in Paris," the 27-year-old said on his website.

"Thankfully my foot is 100 per cent healthy now and I am back in full training," he continued.

"I hope to be back in competition soon but how soon will depend on my training in the next few weeks. It is important for me to take my time this year as I have three tough years ahead in 2015, 2016 and 2017 as I attempt to defend my world and Olympic titles.

"I definitely plan to compete this season and will continue to work hard with my coach who I have the utmost confidence in to get me fit and ready to compete."

Bolt did not indicate when he would return to competition with the next meet on the calendar in Malmo on Aug 5 now axed for financial reasons.

It is also uncertain whether he will compete in the Commonwealth Games in Glasgow starting end July, where Bolt could win one of the few medals missing from his collection.

His management has said recently that he will race in Warsaw on Aug 23 and Zurich on Aug 28.
