Usain Bolt is fit and firing ahead of the Olympics, according to his agent.

Bolt had worried London organisers as well as his legion of fans when he flew to Munich for treatment by celebrated sports doctor Hans-Wilhelm Muller-Wohlfahrt after training partner Yohan Blake edged him out in both the 100m and 200m at the Olympic trials.

But Bolt’s agent Ricky Simms has attempted to play down fears he is a doubt for the Games, adding the 25-year-old sprinter was merely suffering from tightness in his hamstring.

“He’s back to normal, he’s back in full training and he’s good to go,” Simms said yesterday.

“His body is back to normal. The muscle tightness has gone.”

Simms acknowledged Bolt nursed the minor problem at the Olympic trials at the National Stadium in Kingston.

But after managing to qualify for London in spite of the complaint, the Jamaican was told by his coach to fully recover before he can prepare to defend his 100m, 200m and 4x100m crowns.

“He had a tight hamstring during the trials and that’s why possibly he didn’t push as hard as he could have,” added Simms.

“He was just protecting that. The main thing at the trials was to get through.

“His coach decided that he needs to get a little bit of massage and treatment on that and rest up, and then train again hard next week so that he’s ready for the Olympic Games.”
