Asafa Powell has insisted that he will be fully fit for the Olympic Games after withdrawing from the London Grand Prix with a groin strain.
The Jamaican was due to face Tyson Gay over 100 metres at Crystal Palace, but had to pull out of the event for the second year in a row.
The former world record holder has claimed that he "cannot take any risks" ahead of the Olympic Games.
"I've been carrying some soreness in my groin since the Olympic trials and have been unable to train at 100%," said Powell.
"I need to ensure I'm ready for the Games and cannot take any risks,
"I will be ready in August."
The 29-year-old is the fourth-fastest man in the world this year behind Yohan Blake, Usain Bolt and Justin Gatlin.
