Usain Bolt announced that he will not participate in the upcoming Golden Spike meet in Ostrava, and Diamond League meet in Paris, while also remaining doubtful for the Commonwealth Games.

Bolt initially considered returning to competition in the Diamond League in July, but the Jamaican track superstar announced on his official website that he is not yet ready to race again.

The 27-year-old world champion said that he is already 100 percent healthy, but he decided to skip the two upcoming meets after failing to get enough training after recovering from a foot injury.

"My foot is 100 percent healthy now and I am back in full training.  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," Bolt announced. "These are great events that I have competed in many times in the past and I plan to run in many times in the future."

Bolt said that he is unsure when he could make his much awaited return, fueling speculation that he could also miss the upcoming Commonwealth Games where he is expected to be one of the favorites to win the 200m race scheduled on July 30.

The six-time Olympic champion admitted that he is taking a cautious approach for his return from the foot injury because he is anticipating a very busy schedule in the next three years. He is set to defend his world title in Beijing next year, and his Olympic title in Rio in 2016.

Bolt won the 100m, 200m, and 4x100m relay gold during the 2008 and 2012 Olympics in Beijing and London, respectively, while also capturing the title in the same events in last year's world championships in Moscow.

"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," Bolt added. "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."
