OLYMPIC champion Usain Bolt will be fit to defend his 100m, 200m and 4x100m crown at the forthcoming Olympic Games in London.

Bolt had raised concerns among his fans when he flew to Munich for treatment by sports doctor Hans-Wilhelm Muller-Wohlfahrt after training partner Yohan Blake edged him out in the 100m and 200m Olympic trials.

However, his agent Ricky Simms has played down fears that he is a doubt for London, insisting the 25-year-old 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.

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

Bolt nursed the minor problem at the Olympic trials in Kingston, but after managing to qualify, was told to fully recover by his coach before preparing to defend his titles.

“He had a slightly 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 and get on the team for the Olympic Games.

“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.”
