Jamaica’s track team doctor Winston Dawes says, that Usain Bolt and Yohan Blake are both "fit and raring to go" at the Olympics.

He has shrugged off suggestions Bolt will miss the Games with injury and promised "something fantastic" from the sprint pair.

Reigning 100m and 200m champion Bolt is understood to have been suffering with niggling leg and back problems.

But Dawes added that both of them are at the top of their game, and that if the conditions are ideal, then they may see something fantastic, like records breaking.
