The agent of Usain Bolt has confirmed that the sprinter is fit for London 2012.
There had been concern that the world's number one was suffering from an unknown injury problem but this has been dismissed by Ricky Simms.
Bolt was recently beat in the Jamaican Olympic trials by his training partner Yohan Blake in both the 100m and 200m races and this gave rise to speculation that something could be wrong.
"He's back to normal, he's back in full training and he's good to go," Simms stressed to the Daily Telegraph.
"He had a slightly tight hamstring during the trials and that's why possibly he didn't push as hard as he could have. He was just protecting that. The main thing at the trials was to get through and get on the team for the Olympic Games."
However, the agent admitted that Bolt had visited the world-renowned sports doctor Han-Wilhelm Muller-Wohlfahrt in Germany but that this had been a pre-planned appointment and was related to a long-term back condition.
The Olympic 100m final takes place on August 5th at the Olympic Stadium and it is hoped that Bolt could break his own world record of 9.69 seconds –which he set in Beijing in 2008.
Meanwhile, many athletes involved in the Games will be taking part in a final Grand Prix in London this weekend. Tyson Gay and Asafa Powell have confirmed that they will go head to head in the 100m – just a few weeks before the two sprinters take part in the Olympics.
There are still tickets available for those staying in luxury hotels in London and the meet takes place at Crystal Palace.
