Powell promises to be at Games after Diamond exit

Former 100m world record holder Asafa Powell has insisted he will be fit to run at the Olympic Games after withdrawing from the London Grand Prix with a groin strain. Powell was due to face American Tyson Gay at Crystal Palace on Friday evening, but has now pulled out of the event for the second year in a row. \"I\'ve been carrying some soreness in my groin since the Olympic trials and have been unable to train at 100 percent,\" the 29-year-old Powell said. \"I need to ensure I\'m ready for the Games and cannot take any risks,\" the Jamaican sprinter added. \"I will be ready in August.\" The London Grand Prix is part of the IAAF\'s Diamond League series of track and field meetings.
