Jamaica sprinter Usain Bolt has insisted that he is working hard to be fully fit for the upcoming Commonwealth Games in Glasgow amid reported concerns over his fitness.
The fastest man in the world has missed more than two months this year with a foot injury that required surgery, and he will only take part in the 4x100m relay.
"It's been rough, but I've been through it a couple times so I know what it takes to get back so I'm just pushing on and working towards what's necessary for this season," BBC Sport quotes Bolt as saying.
Bolt has won six Olympic gold medals.
